    Bug of the Month: Mourning Cloak Butterfly

    by Janis Butler, Master Gardener Volunteer

    Ever wonder where butterflies spend the winter? Monarchs fly to Mexico but what about the rest?

    undefined

    Many of them stay right here, though it’s hard to believe such a delicate creature could survive the hazards of a winter in the Northeast. One beautiful example is the Mourning Cloak (Nymphalis anitopa), who is different from other butterflies in several surprising ways. For one thing, she lives much longer than most butterflies – 10 to 12 months.

    Starting now, in fall, adult Mourning Cloaks are looking for places to spend the winter. Loose tree bark, tree cavities and leaf piles are their favorite spots. Picture the loose bark on familiar trees like river birch (Betula spp.), American hop hornbeam (Ostrya Virginiana), shagbark hickory (Carya ovata), oak (Quercus spp.), walnut (Juglans spp.), American hackberry (Celtis occidentalis), willow (Salix spp.) and alder (Alnus spp.) The Mourning Cloaks snuggle under the bark and hibernate until spring. Bark offers protection from the elements and perfect camouflage since butterflies’ closed wings are the color of bark or dried leaves.

    If trees are not handy, leaf litter is another great spot for them to hibernate, and another reason for humans to leave leaves alone in fall: no mowing or blowing or bagging. Wait until spring for clean-up. It’s hard for us to change our habits but worth it for the sake of insects whose numbers are diminishing globally.

    Mourning Cloaks will be among the earliest to wake up next spring and when they emerge from hibernation, they will immediately mate. The male dies after mating but the female lives a while longer, laying eggs on trees that will provide the proper diet for her offspring (willow species, elm, cottonwood, paper birch, hackberry), and then she dies too.

    The eggs are startling! About 250 bright amber to olive-colored eggs are lined up on twigs like corn on the cob. They all hatch in about two weeks and begin to feed, sometimes on each other. This gives the cannibals a nutritional boost and reduces competition, though it can’t be pleasant for late-arriving hatchlings. The victorious young caterpillars will often huddle together in a mass and vibrate, twitching in sync to give potential predators the impression of something much larger.

    Eventually the larvae consume the leaves of the host tree and then pupate. They travel a long way — up to 50 feet — from the host plant in order to find the perfect spot to create the grey, bristly chrysalises that are often seen hanging from twigs in early summer.

    When the adult butterflies emerge in a couple of weeks, they feed for a while and then— amazingly — enter a stage of estivation or summer sleep! Why this long, sleepy pause just as they enter adulthood? No one knows for sure, but it’s been suggested that this period of quiet saves them from the challenges of summer heat, dryness and predators. When they wake up in late summer and early fall, the hunt for a winter home begins and the cycle continues. This is an unusual life cycle for a butterfly but the Mourning Cloak’s uniqueness doesn’t stop there.

    Rarely, if ever, do Mourning Cloaks visit flowers. Like other butterflies, they have long tongues that curl up under their chins when not in use, but they don’t use them for nectaring. Instead, they schlurp up tree sap, juice from rotting fruit like mulberries, and aphid honeydew. You might also see them on mud or dung piles, or drinking the dew caught in willow catkins.

    They can fly at lower temperatures (50 degrees) than other butterflies and as a result they sometimes wake up in winter, warmed because their dark outer wings act as solar collectors. And their bodies are “hairy,” with hair-like bristles for insulation. As if that wasn’t enough, they can also contract their flight muscles rapidly to generate heat.

    Because their folded wings resemble tree bark or leaf litter, predators must look hard to find them. If their wings have not reached the right temperature for flight when they emerge in winter, and they sense that a bird or other hungry critter is about to eat them, they have very useful ability to play dead: they can drop like a stone from a tree trunk and vanish into the leaves below. Another trick is to open their wings suddenly, with a flash and a click, sufficiently loud to drive the predator away.

    What can you do to help Mourning Cloaks survive? Most importantly – leave leaf litter alone in fall. If it’s a problem on the lawn, rake it gently into piles at the edges of the lawn and use it as mulch in spring. Plant trees that Mourning Cloak larva require: willow, poplar, cottonwood, birch, hackberry. Leave some overripe fruit (bananas work) in a shallow dish now and also on warm days in winter. Another dish with wet sand or pebbles will provide the water and minerals they need. Thanks for helping!

    Stress is a Tree-killer

    by Jennifer Lerner, Senior Resource Educator

    As we approach winter your trees may be suffering. But you may not know until it dies next spring!

    undefined

    Consecutive years of fall droughts and defoliation by spongy moth puts trees at risk. Add to that poor nutrition and rock soils with little room for root development and you may have a perfect recipe for tree stress.

    How does stress and drought kill trees? Besides the obvious concept that they are simply lacking the water or nutrients they need, there are other surprising side effects. The tree’s vascular system is filled with watery fluid, or “sap.” Sap carries not only water and nutrient, but defense chemicals and stress hormones as well. Insects and pathogens are adapted to detect those stress chemicals and zero-in on trees in trouble. Without ample sap carrying defense chemicals, the trees defenses are down and invasion by insects and pathogens is just that much easier.

    Some insects are adapted to hearing a tree in drought stress. How is that possible! The tree’s vascular system is made of millions of microscopic tubes like straws that are filled with watery sap. As a drought worsens and the tree begins to dry out, tiny air bubbles form in those microscopic tubes. This process is called cavitation and it happens under pressure. Cavitation makes a tiny but detectable noise and, you guessed it, some insects can hear and feel this happening. Without ample sap, the tree cannot deliver the defense chemicals that ward off these attacks.

    With many successive years of drought tree vigor begins to wane. You may see this as the tree begins to make smaller leaves, copious fruits or seeds. Branches may not grow as quickly or as long as they used to. What leaves there are may exhibit summer scorch symptoms because of insufficient water reaching leaves in dry weather.

    With continued stresses, branches begin to die, and at the same time the root system of the tree is reduced because the crown is producing inadequate food for good root expansion and growth. These processes continue into a downward spiral, usually resulting in the continued decline and eventual death of the tree over a period of 2-15 years. In most cases, once the tree has tipped the balance of not providing sufficient carbohydrates for continued growth of the tree, it cannot recover.

    Since the tree is dormant you may not see that the tree is dead until spring, when the tree either doesn’t leaf out or produces leaves that quickly wilt and die.

    What can you do to reduce drought stress and other stresses? First, when you plant a new tree, choose one well adapted to the site conditions and water it throughout its first year of establishment. For already established trees plan on watering them during periods of dry weather. If you have water restrictions this may be impossible. But if you can water it’s better to water deeply and infrequently rather than frequent, light waterings. Watering deeply allows water to reach the feeder roots most of which are in the top 6”-8” of soil. You can continue to water until the leaves have fallen from your trees, or, if it is an evergreen, until the ground freezes.

    As Food Assistance Uncertainties Loom, Pantries Provide Vital Support

    by Ruby Koch-Fienberg, Ag & Food Systems Coordinator

    Many in our community are feeling hopeless as food insecurity reaches crisis levels, and recent news confirms that SNAP benefits—a lifeline for nearly 3 million New Yorkers—are being paused due to the federal administration’s refusal to release billions of dollars in reserve to aid roughly 42 million people at risk of hunger.

    In 2023, 12,823 households, or 37 percent of Putnam’s population, were below the ALICE (Asset Limited, Income Constrained, Employed) threshold. That means more than one in three of our neighbors finds it difficult to cover the basic cost of living. Funding cuts and pauses are only making things harder. As more neighbors face hunger, local food pantries are already witnessing a dramatic surge in demand, and this is expected to intensify in the coming weeks. If you are looking for the closest pantry to access resources, you can find an updated list  HERE.

    At Cornell Cooperative Extension Putnam County, we are committed to strengthening our local food system, but we urge everyone: please support your local pantries, which will be pivotal in helping families bridge the gap during this crisis.

    Donating money, toiletries, and basic essentials makes an immediate impact—before bringing food, always check your pantry’s website or call to see what's most needed, as priorities may change. Together, we can address urgent needs and help our neighbors weather this incredibly difficult moment.

    Bountiful Meals freezers across the county are available to anyone. Click  HERE to see the locations and hours.

    Below is a list of food pantries in our area:

    • New Life Christian Church, Brewster: (845) 278-9407
    • St. John the Evangelist, Mahopac: (845) 628-2006
    • Salvation Army Peekskill-Food Pantry/Soup Kitchen: (914) 737-0280

    Cloverbud Sprouts Visit Farm Market

    Our Cloverbud Sprouts 4-H Club are learning a lot about farms. In October, they visited the Kent Lakes Farm Market to see how they make a profit by selling their goods to the community. The Sprouts were allowed to pick pumpkins from the shelves and paint them for Halloween. As a surprise, staff at the market set up a pumpkin photobooth for the Sprouts to take pictures with their creations.

    "I loved painting pumpkins with my friends," said Scott Purdy, an 8-year-old Sprout. "My pumpkin was a candy corn but instead of yellow I used gold, and the twins in my club made black pumpkins with frogs on them."

    Rooted in Learning Grant Connects Students to Food

    The Rooted in Learning: Growing Healthy Futures with Farm to School Education grant's goal is to cultivate deeper, more intentional connections between the cafeteria, classroom, and community in support of farm-to-school initiatives. Students in North Salem and Brewster had their first visit with an orchard owner to learn about apples. This visit is one of several planned during the school year with an aim to connect students with local agriculture.

    Jinny St. Goar from Once Munsee Orchard in Wallkill, NY, made trips to both Pequenakonck Elementary School and CV Starr to talk about her orchard and to share a variety of apples with students.

    Before the tasting, St. Goar shared why apples deserve their healthy reputation. "Apples are very rich in antioxidants, fiber, vitamin C, and potassium," said St. Goar. She also explained how apples and roses are in the same plant family, the role of honey bees in pollination, and how scientists create new varieties, such as the Evercrisp they were sampling.

    Implementation of this grant is a partnership with Harvest NY and Cornell Cooperative Extension Putnam County and the North Salem and Brewster Central School Districts.

    Educational activities include Farmer Visits and taste tests in the cafeterias, participation in Ag Literacy Week, farm to school monthly newsletters, and school-based clubs. It also includes initiatives like NYS 30% procurement (the NYS 30% Initiative increases the reimbursement schools receive for lunches from 5.9 cents per meal to 25 cents per meal for any district that purchases at least 30 percent ingredients for their school lunch program from New York farms. School districts that have reached the 30 percent threshold can apply for reimbursement) and New York Thursdays (which is a locally sourced meal initiative that brings farm-fresh New York State foods to schools and institutions on one or more Thursdays a month throughout the year).

    Keep Food Safety in Mind this Thanksgiving

    from United States Department of Agriculture

    Turkey is the most popular dish during Thanksgiving celebrations, yet there are many inexperienced cooks who will be in the kitchen. The U.S. Department of Agriculture (USDA) encourages consumers to practice food safety throughout the entire Thanksgiving process, from the grocery store to the dining table.

    To keep your Thanksgiving food safe, follow this guide:

    Shopping

    Bacteria can multiply to dangerous levels if perishables, like turkey, are left in the Danger Zone (temperatures between 40 F and 140 F) for too long. Pick up your turkey and other perishable products at the end of your grocery shopping so they stay cold as long as possible. Pack perishables in insulated bags with cold sources if the commute home is longer than an hour and place them in the refrigerator as soon as you get home.

    Make sure the packaging of your turkey is not torn or leaking. Juices from raw poultry can cause cross-contamination of harmful bacteria that can get you sick. Place turkey, and other raw meat products, in plastic bags and in a separate part of your shopping cart to prevent harmful bacteria from spreading.

    Thawing

    A frozen turkey can be safely thawed in the refrigerator or in cold water:

    When thawing in a refrigerator at 40 F or below, allow roughly 24 hours for every 4 to 5 pounds. Consider putting the turkey in a container or dish to contain juices that may leak.

    When thawing in cold water, allow roughly 30 minutes per pound. Submerge the wrapped turkey into the cold water and change the water every 30 minutes until the turkey is fully thawed. Once thawed, cook the turkey immediately.

    Preparing

    When it is time to prepare the turkey, keep in mind that turkeys may contain bacteria that cause foodborne illness. Keep the turkey and its juices separate from foods that won’t be cooked and fully clean and sanitize surfaces that come into contact with the turkey and its juices. A USDA study found that about 30% of consumers did not successfully clean and sanitize kitchen surfaces around meal preparation.

    Washing a turkey is risky because it can spread bacteria to your sink and other nearby surfaces. If you choose to wash it, make sure to fully clean surfaces with soap and water afterwards and then sanitize using a sanitizing solution.

    Cooking

    There are many ways to cook a turkey, but one thing remains consistent: the turkey needs to reach a safe minimum internal temperature of 165 F, as measured by a food thermometer, in three places — the thickest part of the breast, the innermost part of the thigh, and the innermost part of the wing. Always use a thermometer to make sure the turkey is fully cooked even if the turkey has a pop-up temperature indicator. If stuffing your turkey, the stuffing must also reach 165 F in the center of the stuffing.

    Serving

    When serving food to groups, remember the two-hour rule. Perishable foods that have sat out at room temperature for more than two hours are unsafe, due to bacterial growth, and must be discarded. When you are serving food, keep your hot food hot and cold food cold. This will keep it from developing harmful bacteria. Hot foods such as turkey, macaroni and cheese, stuffing, mashed potatoes and gravy must be kept at or above 140 F and you can do so by serving them in warming trays, chafing dishes, slow cookers, etc.

    Cold foods such as salad, cranberry relish, deviled eggs and cold dips must be kept below 40 F and you can do so by serving them in trays or bowls nestled over ice. Remember to replace the ice as it melts. You can also serve cold foods by dividing them in small portions and serving them a portion at a time, keeping the remainder in the refrigerator.

    Leftovers

    Leftovers are arguably one of the best parts of Thanksgiving. For leftovers to be safe to keep, they must be refrigerated within two hours of serving or have been kept hot at or above 140 F or cold below 40 F. Discard any foods that sat out for more than two hours at room temperature because bacteria that cause foodborne illness could have reached dangerous levels. If you have turkey leftovers, carve the bird into smaller pieces and place them into small, shallow containers so the meat can cool evenly and quickly.

    If you have food safety questions while planning and preparing your Thanksgiving feast, call the USDA Meat and Poultry Hotline at 1-888-MPHotline (1-888-674-6854) or email MPHotline@usda.gov, 10 a.m. to 6 p.m. (Eastern Time), Monday through Friday to reach a food safety specialist in English or Spanish. The Meat and Poultry Hotline is also open on Thanksgiving Day from 8 a.m. to 2 p.m. (Eastern).
