    Bug of the Month: Organ Pipe Mud Dauber Wasp

    by Janis Butler, Master Gardener Volunteer

    undefined

    You’re probably seen her structures and admired them but perhaps didn’t know the name of the architect. She’s a gifted builder, masterfully combining form and function and putting a lot of herself into her work. After selecting only the finest materials for her creations, she binds them together with her own saliva.

    We’re referring to the works of the Organ Pipe Mud Dauber Wasp (Trypoxylon politum) and the architecture in question is the long, thin tubes of mud that she artfully positions side by side in sheltered spots, under eaves or in abandoned buildings, usually near a source of damp soil.

    This beautiful inch-long wasp is patent-leather black — iridescent in some light — with purple wings, a thread-like waist and white or pale yellow “ankles” on her hind legs, easily visible as they dangle below her while she flies. Like all non-aggressive solitary wasps who have no need to defend their nests, she is docile and only stings if caught in clothing or mishandled. The males don’t even have stingers.

    Building the Organ Pipes

    When constructing her characteristic “organ pipe” nest, she sources mud carefully. It must be wet and pliable, fine-grained, and rich in clay content. So astute is her choice that human potters have been known to follow mud daubers around to discover the source of their high-quality clay.

    Once she’s found an acceptable source, she lunges at the mud with her mandibles spread, scooping some up and forming a ball with her mandibles and forelegs. Each mud ball is tiny, so it takes many trips to her clay site to gather enough for the pipes, she usually makes five to seven pipes, stuck tightly together, each with three to six cells.

    Once back at the nest site, the wasp mixes the mud with her saliva, which acts as an adhesive and produces a cement-like mixture that hardens when dry. She then vibrates her body, producing a high-pitched buzzing sound to help pack the mud tightly, which increases the density and strength of the nest walls. She uses her forehead to smooth out, prod and smear the balls into place as she builds the walls, one cell at a time, eventually sealing each cell off before starting another immediately below it, resulting in the pipe-like appearance. The tubes are durable and waterproof, usually a shade of beige or gray, depending on the source of the clay.

    Provisioning the nest

    After the completion of each cell’s walls, she begins to hunt for food for her offspring. Organ Pipe Mud Dauber hatchings (tiny grubs) must have fresh food — specifically, live spiders — in order to survive. So the mother’s work is preordained: she must find mid-sized orb weavers or some similar species and bring them back to the nest alive.

    Depending on the size of the spider, she may cram 5 to 20 (30 have been recorded!) into a single cell in the pipe. The spiders are immobilized by her paralyzing venom but remain alive until consumed by the emerging wasp larva. This is tough on the spiders, who are considered beneficial insects in our gardens, but does help keep spider numbers in balance.

    Once the wasp is satisfied that her offspring will be well-nourished, she mates with a waiting male, lays an egg on one of the spiders, and seals off the cell. She then flies off to gather mud for the next cell.

    In the process of finding spiders for her children, the mother wasp keeps up her own energy needs with visits to flowers for nectar, making her an important pollinator. While she is busy building and provisioning, the male wasp stays near the entrance to the nest, waiting to mate but also guarding against intruders, parasites, and other males, a rare instance among wasps of fatherly participation in the raising of his young. He may even help the female in nest construction. The female’s chores are limited to nest buildings, food procurement for the offspring, and egg-laying. She spends no significant time at the nest.

    Life of the Larvae

    The eggs hatch in a couple of days and the emerging wasp larvae begin consuming all the spiders, leaving behind only a few indigestible leg parts. The now-plump larva then creates a cocoon for itself and enters a prepupa state (a state of suspension between larva and pupa). It remains in this state until ready to morph into its final adult form the following year, chewing its way out of its cell.

    If female, she will begin to build her own nest within a couple of days of emerging. If male, he will wait around for his paternal duties to begin. The mother wasp determines the sex of her offspring by holding sperm in a specialized organ (spermatheca) and deciding whether to release it as the egg passes, fertilizing it for a female or leaving it unfertilized for a male. She typically provides more spider food for the females, themselves future egg-layers, who are usually larger than the males.

    Despite careful guarding by the male wasp, the developing larvae are preyed upon by many hungry foes. Parasitoid wasps, cuckoo wasps and others devour the Organ Pipe Mud Dauber Wasp larvae directly. Other insects steal the spiders stored in the nest, thereby starving the wasp larvae. And birds, especially the tufted titmouse, will break open the tubes to feed on the larvae. The holes they make are often mistaken for the larvae’s exit holes.

    How Can We Help These Beneficial Insects?

    Don’t disturb the “organ pipes” until you see clear signs that the new adult wasps have departed in late spring or early summer. You should see exit holes on the sides of the tubes, one hole for each emerging wasp. The nests are only used for one season and, once they’ve fulfilled their purpose, can be easily removed by humans.

    Avoid killing spiders. They are a gardener’s friend and valuable food source for Organ Pipe Mud Dauber Wasps.

    Avoid using insecticides, which might kill spiders as well as wasps, especially when pollinators like the Organ Pipe Mud Dauber Wasp might be present.

    Provide water in summer, especially during times of drought. Keep a shady mud patch watered, perhaps at the edge or behind your garden.

    Pedal Your Way to Environmental and Personal Wellness

    from UF/IFAS Extension, Sarasota County, adapted by Rachael Paradise, Communications Coordinator

    undefined

    May is National Bike Month, a celebration of the bicycle and its extensive impact on wellness, transportation, and sustainability. Bike to Work Week is May 11-17, with Bike to Work Day on Friday, May 15. Whether for health, environmental, social or economic reasons, bicycling can be a great way to get around.

    Benefits of Biking
    Environmental: Biking reduces your contribution to climate-changing pollution like carbon dioxide, which are produced by cars and trucks. Swapping a bike trip for a vehicle commute will substantially reduce the greenhouse gas emissions (pollution) you create, while also saving you gas money and preventing wear-and-tear on your vehicle.

    Wellness: Along with decreasing your carbon footprint, biking has several health and wellness benefits. Biking can help strengthen your heart, lungs, and bloods vessels by providing low-impact exercise. Other potential benefits include increases in flexibility and strength as well as coordination and balance. Getting outside also reduces stress and promotes mindfulness.

    Bike Safety Tips

    • Ride in the same direction as traffic and stay as far to the right as possible. Use bike lanes whenever you can.
    • Cross at intersections and never pull out into the roadway from between parked cars.
    • All bicycle riders and passengers should wear a helmet. Always wear a properly fitted helmet and securely fasten the strap.
    • Be seen. Wear neon, fluorescent or bright colors when riding and wear something that reflects light (reflective shoes, reflective tape, etc.).

    For many of us, biking to work isn’t an option, but there are plenty of trails in the area that offer miles of scenic views from rivers and lakes to forests and fields to city skylines!

    Below are some bike-friendly trails, but be aware, you may be sharing these trailways with walkers, joggers and, in some cases, horses.

    Battery Bikeway
    The Battery Bikeway connects the Hudson River Park Bikeway to the East River Esplanade making a 31-mile uninterrupted waterfront bicycle path that wraps Manhattan.

    Bronx River Greenway
    The Bronx River Greenway runs for 22 miles along the Bronx River, traveling from the mouth of the East River north to the Kensico Dam, providing views of the natural history of the area.

    Harlem Valley Rail Trail
    Paralleling the Connecticut and Massachusetts borders, which lie only a few miles away, the Harlem Valley Rail Trail is a beautiful 26.2-mile wooded pathway along the former New York & Harlem Railroad.

    Heritage Trail (NY)
    The Heritage Trail is a 10-foot-wide trail on the right-of-way of the former Erie Railroad. When completed, the trail will extend from the City of Middletown to the Village of Harriman. The trail features sections of both asphalt and limestone surface. The current 19.5-mile trail winds through a bird/wildlife sanctuary, historic landmarks, murmuring streams, rolling meadows and friendly communities.

    Hook Mountain/Nyack Beach Bikeway
    The Hook Mountain/Nyack Beach Bikeway is a scenic trail that runs almost 5 miles along the Hudson River in Rockland County. The trail runs through Hook Mountain State Park and Rockland Lake State Park between Haverstraw Beach State Park and Nyack Beach State Park.

    Hudson Valley Rail Trail
    The Hudson Valley Rail Trail is a 9-mile Empire State Trail section that begins in the Town of Lloyd, at Walkway Over the Hudson State Park, which is a spectacular 1.5-mile park built on an historic railroad bridge high above the Hudson River.

    Hutchinson River Greenway
    The Hutchinson River Greenway offers a convenient alternative to the Hutchinson River Parkway, which it closely follows. Although adjacent to the busy thoroughfare, trees have been planted along the route to help beautify the path and trail-goers can also catch glimpses of the river on their journey.

    Kennedy Trail
    The Kennedy Trail gently traces a former New York Central Putnam Division line. Stroll through a mixed hardwood forest and the edges of a pond. During the fall, this is a nice spot for leaf peeping. The area around John F. Kennedy Catholic High School is private, so please stay on the established path.

    Putnam Trailway
    The Putnam Trailway is a 9-mile Empire State Trail section and is an off-road paved trail, welcoming bicyclists and walkers of all abilities. This scenic rail-trail begins in Mahopac, at a trailhead parking area at the intersection of Croton Falls Road and Mud Pond Road. The trail follows the Putnam Trailway north from there, winding through wooded areas, past scenic lakes, and through small communities. The trail passes through Carmel, and ends slightly west of the Village of Brewster, at the intersection of Carmel Avenue (Route 6) and Putnam Avenue.

    Walkway Over The Hudson
    Walkway Over the Hudson is a steel cantilever bridge spanning the Hudson River between Poughkeepsie, on the east bank, and Highland, on the west bank. Built as a double track railroad bridge, it was completed on January 1, 1889, and formed part of the Maybrook Railroad Line of the New York, New Haven and Hartford Railroad. It was taken out of service on May 8, 1974, after it was damaged by fire. It was reopened on October 3, 2009, as part of the new Walkway Over the Hudson State Historic Park.

    'Tis the Season for Fleas and Ticks

    from Agriventures Agway

    Text Next to Image Example

    undefined

    Cats and dogs can be warm, wonderful companions. However, those companions will often most likely bring other parasitic creatures into your lives that are not at all welcome. Fleas and ticks, aside from the often-intense irritable itching from their bites, can also lead to severe allergies, and can infect both your pets and you and your family with some very serious diseases.

    Understanding the Pest Problem

    For both cats and dogs in the U.S. the cat flea (Ctenocephalides Felis) is the most common flea and the one with which your pets are likely to be infested. The cat flea will feed on many animals, including humans and once an infestation is established it can be difficult to eradicate. Your pets are likely to become infested through close proximity to other infested animals, infested bedding, furniture, or flooring, and in the case of a very heavily infested property, even the lawns; fleas can cause anemia, skin infections, and can also introduce tapeworms into their host.

    Ticks (part of the spider family) can pose a very real threat and are frequently the culprits for infecting their hosts with life threatening illnesses such as Lyme Disease and Rocky Mountain Spotted Fever. Your pet is most likely to pick up a tick as it moves through tall grass. Once a tick has fed it will drop off and look for somewhere for shelter and to establish an infestation. Unless you are vigilant, this could be your home.

    Identifying Flea and Tick Infestations

    According to the University of Kentucky, College of Agriculture, fleas account for over "half of all dermatological conditions requiring veterinary assistance." Identifying a problem before it becomes established will save your pets and possibly your family discomfort and maybe save you some money too. Check your cat and dog regularly, particularly around the armpits, the base of the tail, and the groin. Also watch for signs of your pet excessively scratching, skin damage, bald patches, black dirt like granules (flea feces) in their fur (a flea comb is useful for this), and a dry or flaky skin condition. If you or your family have been bitten by an insect repeatedly, especially around the ankles, it is likely to be fleas; check the furnishings and the carpets.

    Ticks are more commonly a problem for dogs rather than cats, but do not depend on this generality. Check your pets when they come in, especially during springtime when ticks are more active. A tick will appear as a small dot on your pet's skin and will look almost like a growth if it has been feeding for some time. Remove the tick carefully, but not with your bare hands. Use tweezers (there are special tweezers available for tick removal) or resort to commercial products, such as sprays, dips, shampoos, or powders if your pet is heavily infested. If your pet has a tick or ticks, check your home; favorite places for ticks to take up residence are in the furniture, and behind baseboards and door moldings.

    How to Prevent Pet Ticks and Fleas
    The best way to control fleas and ticks is not to get them at all, while this is probably unlikely during the lifetime of your pet, there are steps you can take to turn the odds in your favor:

    • Be vigilant but work on the premise that your pets will get fleas and/or ticks.
    • Consult with your vet as to what solutions are most appropriate for your pet, especially if it is old, very young or pregnant.
    • Treat your pet or have your vet administer to your pets regularly a reputable, safe commercial product such as Frontline or Advantix; unless the label says otherwise, never use cat products on dogs or vice versa; always follow the product's directions.
    • Buy a reputable, safe flea/tick collar for your pet; replace it according to directions. Agriventures Agway recommends and sells Seresto collars, which last up to 8 months!
    • Wash your pet's bedding and soft toys regularly with hot water.
    • Regularly vacuum all areas used by your pets and close by frequently; seal and discard the vacuum bag in an outdoor container and/or clean the vacuum thoroughly.
    • If you acquire used animal bedding, toys or even used bedding and furniture for your family assume it is infested and wash/treat for fleas accordingly.

    What to Do If You Find Fleas and Ticks in Your Home

    There will probably be occasions when even the best precautions fail and your pets and probably your home too, will have a flea or tick infestation. One of the most important things to remember in the case of an infestation is that if your pets spend a lot of time indoors then the overwhelming majority of the fleas and ticks will not be on your pets, they will be in your home. You will need to:

    • Clear the floor area.
    • Take all pet bedding and soft toys and clean or throw it out.
    • Vacuum, everything. You want to suck up as many of the adults, larvae, and eggs as you can; vacuuming will also raise the nap of the carpet thus making any chemical treatment penetrate further. For ticks, pay particular attention to cracks, crevices, and baseboards.
    • Discard the contents of the vacuum in a sealed bag in an outside container
    • Be aware that the use of some products will require that you leave your home for several hours.
    • Treat your pets for fleas and or ticks at the same time as you do your home.

    If the infestation is particularly severe you may need to treat your yard area too. Consult with your vet and/or your local exterminator as to your options.

    When you are going to look for an insecticidal solution to fleas and ticks, take expert advice as to what to use; pet sickness problems have occurred with some products. And, while there are a host of options available to you it is often the case that no one particular solution will do the job in every case; be prepared to be flexible as to the flea and tick control methods that you choose to deploy.

    Painting Bare Wood is the Best Defense Against Carpenter Bees

    from University of Maryland Extension and Penn State Extension

    Text Next to Image Example

    undefined

    Carpenter bees are a native species and like other native bees they are important pollinators, are not aggressive, and are only noticeable in late spring-early summer.

    Control is not necessary unless they are damaging wooden structures. Signs of carpenter bees around your home or garden:

    • Sawdust piles below perfectly circular holes drilled into wood surfaces around your home.
    • Large, shiny, black, and yellow bees buzzing and flying around your head.
    • Fan-shaped, yellow, or moldy stains on the sides of a structure.

    Carpenter bees do not eat wood; they eat flower nectar and pollen. The holes they bore into wood are nests for their young. Eastern carpenter bees are large bees approximately 0.75-1 inch long. The thorax or midsection is covered with yellow fuzz. The abdomen, or the hind section, is shiny and black. Females have a black face and a dense brush of black hairs on their hind legs. Males have a yellow faces.

    Carpenter bees are solitary bees. Each female builds her own nest by tunneling into wood. Carpenter bees are often mistaken for bumblebees, which are similar in size. However, the bumble bee’s entire body is covered with hairs, and females have yellow patches of hair on the top of the abdomen.

    In April or May, the female carpenter bee searches for good nest sites. She will reuse and expand an existing nest tunnel or bore her own. The female chews a perfectly circular hole approximately half an inch in diameter. This entry hole extends 1-2 inches into the wood and then turns at a right angle to follow the grain of the wood. The nest, or gallery, is tunneled parallel to the grain of the wood and may extend for 6-12 inches. 

    Once the nest is complete, the female carpenter bee stocks the end of the tunnel with bee bread, which is a combination of flower pollen and nectar. She lays a single egg on the food mass, then seals the cavity, or brood cell, with a mixture of wood pulp and saliva. She repeats this process, filling the tunnel with a line of brood cells, each about an inch long. Each cell contains a food supply and a single egg. During the nest construction phase, male carpenter bees patrol the site to drive away intruders and to fertilize females in the area. Although the males defend their territory aggressively and may alarm people by darting around their heads and buzzing loudly, male carpenter bees have no sting (sting is the correct term for "stinger") and are harmless.

    Prevention is the best approach to deter carpenter bees. By maintaining sound, finished wood surfaces, bees can be prevented from establishing nests around your home. Painted surfaces are unattractive to nesting bees. Nail holes and cracks should be filled with caulk or putty before painting. The best times to treat and repair damaged wood and minimize the killing of these pollinators would be late summer (after the summer emergence and before hibernation) or early spring before nest building begins. Carpenter bees are usually searching for nest sites in April-May. Non-wood surfaces and coatings, such as vinyl or aluminum siding will exclude carpenter bees entirely.

    Established nests can be eradicated by entirely removing and replacing the affected wood with a painted or otherwise unattractive (to the bees) surface. If tunnels are present treatment with an insecticide and sealing of the tunnel is a control option. Wasp, hornet, and bee aerosol formulations sprayed into the holes are effective. Apply the aerosol material into the tunnel entrances and along exposed surfaces. There are also insecticide dust formulations labeled for carpenter bee control. Dust is effective when small amounts are puffed into the tunnel. Chemicals are often repellent to the bees in large quantities, so the objective is to lightly treat the inside of the tunnel entrances. In a properly treated tunnel, the returning bee spreads the compound throughout the tunnel and receives a lethal dose in the process. If pesticides are overused to the point of repellency the bees may avoid all contact with the tunnel and start over again in a nearby location. Read and follow all label directions. A week after treating the tunnels, the carpenter bees should be inactive, and wood can be caulked and repainted. Tunnels must be pre-treated with a pesticide before caulking or the bees will chew through the plugs and reemerge. If the wood surface as a whole is not improved, bees may reinfest the same area.

    If you choose to apply pesticide while the bees are active, wait until the female leaves the nest before application. Although the bees will not sting in defense of their nests, they often tumble out of the tunnel in response to the chemical. Treat for carpenter bees in the spring, just as the bees become active or in the late summer. Hire a pest control company if the carpenter bees are situated in an overhead, awkward-to-reach place, or if treatment is likely to involve the use of a ladder or step stool.

    According to Penn State Extension, an annual springtime application of almond oil over wood surfaces is an excellent deterrent for those who prefer a natural wood finish. These surface treatments make the wood unattractive to the carpenter bee. In addition to reducing the appeal of the wood structures around the home, providing alternative nesting options in the backyard can help further reduce the chances of negative bee-human interactions while providing suitable habitat for these native pollinators. Untreated pine or cedar can be used to lure female carpenter bees away from wooden structures - and it can be arranged as simply or elaborately as desired.

    The 4-H Hay You! Club had a real "hands-on experience" at a private farm in April. They learned how to treat two roosters for scaly leg mites and bumblefoot, two common ailments in poultry. It was a real "spa day" for the roosters who received a warm bubble bath, foot and leg scrub, and a calming Vaseline "mask" for their legs. The Hay You! Club is made possible by a grant from the Putnam County Youth Bureau.

    “We look forward to strengthening our partnerships with the Youth Bureau with more collaborations in the future,” said Brandy Keenan, 4-H Educator.

    Eggplant Omelet
    Here's a delicious Filipino dish of baked eggplant dipped in egg and cooked in a skillet. Try it for any meal!

    Ingredients

    • 2 medium-sized thin eggplant or 1 medium-sized globe eggplant
    • 2 eggs
    • ¼ cup diced onion
    • 2 cloves garlic, minced
    • ¼ tsp salt
    • 1 to 2 Tablespoons vegetable oil

    Directions
    1. Turn oven broiler to high. Place the eggplant on a baking sheet lined with foil for easy clean up. Broil eggplant on the highest rack possible, turning every few minutes, until skin is blackened on all sides. Broilers vary in power, so keep your eyes on it!
    2. Remove eggplant from the oven. Cover with a lid or foil for 10 minutes to let it steam and cool.
    3. In a large bowl, mix together eggs, onion, garlic and salt.
    4. When cool enough to handle, peel the skin from the eggplant but leave the stem on. On a flat surface, pierce and flatten eggplant with a fork. This will let some moisture escape and drain away. Holding the stem, place eggplant in the egg mixture to coat the flesh.
    5. Heat a medium skillet on medium heat. Spread oil to cover the bottom of the pan. When oil is shimmering, move eggplant to the pan.
    6. Pour the rest of the egg mixture over the eggplant. Cook until the bottom has browned, about 5 to 6 minutes. Using a spatula, turn eggplant over and cook until the other side is browned, about 4 minutes.
    7. Serve with a cooked grain, such as rice, and a sauce, such as ketchup or vinegar. Try it with Food Hero Banana Ginger Sauce.
