Purdue Landscape Report: Have you noticed large, messy webs on trees? You may have seen a colony of fall webworms. These caterpillars hatch in mid-July but tend to become more noticeable as the summer progresses. They often eat branches bare of leaves but are they a threat to tree health?

What do they look like?

Fall webworms are small, fuzzy pale-yellow caterpillars (figure 1) that build large, conspicuous white webs in trees in the late summer (figure 2). Their webs stretch over tree branches and grow over the course of the summer. When disturbed, the caterpillars will violently thrash back and forth in a bid to ward off predators.

Fig2. Trees will often have multiple fall webworm webs on them. This photo shows a typical number of webs for a large tree. Notice that the webs tend to be on the ends of branches and that the leaf damage is concentrated close to each web. Photo by Ken Gibson.

What kind of damage do they cause?
Fall webworms eat the leaves of many species of deciduous trees and bushes. This damage occurs late in the summer shortly before the trees normally drop their leaves for fall. Therefore, fall webworms very rarely do serious damage to trees. In most cases the trees will grow their leaves back the following spring. On rare occasions, a tree that is already highly stressed may be further weakened by fall webworm damage. However, most trees, even heavily infested trees, are minimally affected and show no signs of damage the following spring.

Do they need to be managed?
Fall webworm damage generally looks much worse than it is. In general, trees only need to be managed for fall webworm if the owner is concerned about aesthetics. In that case, the easiest means of management is pulling the web off the tree by hand and putting it in a bucket of soapy water or freezing it. Some people may be sensitive to the caterpillars’ hairs so gloves should be worn to prevent contact.

In cases where the webs are too high up to be reached, they can be managed through insecticides. Further instructions can be found here.

Purdue Landscape Report: Now that we’ve reach midsummer, many people tending to small plants and bushes may notice small odd round grey objects attached to their plants that are made by potter wasps. Do you need to do anything about them? Do these nests help or harm your plants? And are they dangerous to people?

What do they look like?
You are more likely to notice the nests of potter wasps than the adults. Potter wasp nests often look, like the name suggests, like a small grey pot (figure 1). They are rounded with a small opening that looks like the neck of a vase and are about the size of a cherry tomato. These wasps will attach their nests to many different surfaces but tend to prefer plant and bush stems. Potter wasp nests are often found hidden behind foliage in bushes.

Potter wasp adults come in a variety of colors but all of them look like small hornets. The most common species found in Indiana are mostly black with pale yellow bands around their abdomen (figure 2).

How do they help plants?
Each “pot” that the wasps build is a tiny nursery for a single wasp. Adult potter wasps lay a single egg in each “pot” and then fill it with paralyzed caterpillars and small beetle larvae. When the wasp egg hatches it has all the food it needs to develop into an adult contained in the pot. Each wasp does a small part to keep down the number of caterpillars in the landscape which can reduce the amount of leaf damage on nearby plants.

Will they hurt me?
Probably not! Potter wasps don’t defend their nests and are generally not aggressive. Unless you actively try to bother them they will probably not bother you. If you need to remove one of their nests, you can simply pull it off the plant or object that it’s attached to. However, since they help with pest control, you may want to either leave the nest be or relocate it to a different section of the landscape.

Does anything else look like the “pots”?
Although the “pots” have a very distinct shape there are a few other things that could be confused with them at first glance. Mantis egg masses (ootheca) and some types of galls are both about the same size as potter wasp nests and also often grey. However, they both lack the vase neck-like opening that potter wasp nests have.

What should I do if I see one?
Let it be! Since these wasps rarely sting and help keep caterpillar populations down leave them alone so that they can continue to act as biocontrol agents. If you think you’ve seen a potter wasp or one of their nests and would like help identifying it, take a picture and either upload it to a community science project like iNaturalist or send a picture to the author of this article.

coyotesJanuary IDNR Wildlife Bulletin Newsletter: It’s that time of year again – coyotes are on the move, and Indiana residents might see them more, but this should not be a cause for alarm.

Coyotes are common everywhere in the state, even in urban areas. Coyotes become more active during winter, and the bare vegetation this time of year increases the chance of catching a glimpse. Young coyotes leave their parents to find a new home, making them more likely to be seen during winter. And in January, coyotes will be looking to breed, making them even more active. Seeing more coyotes does not mean they are increasing in number.

Where people are, coyotes follow. Coyotes like to eat animals and plants that thrive around yards and homes, including rabbits, mice, fruit and squirrels. They thrive around people because of the abundant food that comes with human development.

Coyotes are a common member of Indiana’s urban wildlife community, as are raccoons, red foxes, and opossums. Coyotes are also an important member of Indiana’s wildlife community, helping control rodent populations and cleaning up carrion.

Coyotes typically weigh between 20-30 pounds and are similar in height to a German Shepherd. Winter fur, which is thicker, makes coyotes appear bigger than they actually are, potentially causing concern.

To reduce the possibility of pets having a negative interaction with coyotes or any other wildlife, keep pets leashed, in a kennel with a secure top, or indoors.

Problems between coyotes and people are uncommon. Follow these tips for making your property less attractive to coyotes:

  • Clean up fallen fruit from trees or gardens.
  • Keep garbage secure.
  • Make sure pet food and treats are not left outside.
  • If you see a coyote around your yard, take down birdfeeders; coyotes could be attracted to the rodents eating the seeds.
  • Never intentionally feed a coyote, which could result in its losing its fear of people.

Making a coyote feel unwelcome around people can help maintain its natural fear of humans, but never corner or chase a coyote – you should always allow it to have a clear escape path to get away from you.

If you see a coyote and want it to go away, try to make it uncomfortable:

  • Yell.
  • Wave your arms.
  • Spray it with a hose.
  • Throw tennis balls or small stones at it, but don’t throw anything that could be food, like apples.
  • Carry a jar of coins to shake or a small air horn to make noise.

Purdue Landscape Report: Just as sure as you try to predict the weather, it is likely to change. But going out on a limb, I predict that we will have a bit of a dud for fall color display this year. Not a very risky prediction, considering that many plants already are starting to turn color and/or drop leaves in some areas of the state.

Nyssa sylvatica

So why would the colors be early and/or a bit duller than usual? Certainly, some of the reason why plants display fall colors has to do with the genetic makeup of the plant. That doesn’t change from year to year. But the timing and intensity of fall colors do vary, depending on factors such as availability of soil moisture and plant nutrients, as well as environmental signals such as temperature, sunlight, length of day, and cool nighttime temperatures.

The droughty conditions experienced during much of the second half of summer are likely to have decreased the amount of fall color pigment. Southern Indiana has been particularly parched. Despite recent rains in some areas, much of the state remains designated as abnormally dry to moderate drought. You can check your area’s conditions at the US Drought Monitor for Indiana. Additional maps and data is available at the Midwest Regional Climate Center.

Growing conditions throughout the season affect fall color as does current weather. Colors such as orange and yellow, which we see in the fall, are actually present in the leaf all summer. However, those colors are masked by the presence of chlorophyll, the substance responsible for green color in plants during the summer. Chlorophyll allows the plant to use sunlight and carbon dioxide from the air to produce carbohydrates (sugars and starch). Trees continually replenish their supply of chlorophyll during the growing season.

As the days grow shorter and (usually) temperatures cooler, the trees use chlorophyll faster than they can replace it. The green color fades as the level of chlorophyll decreases, allowing the other colored pigments to show through. Plants that are under stress–from conditions like prolonged dry spells–often will display early fall color because they are unable to produce as much chlorophyll.

Yellow, brown and orange colors, common to such trees as birch, some maples, hickory and aspen, come from pigments called carotenoids, the same pigments that are responsible for the color of carrots, corn and bananas.

Red and purple colors common to sweet gum, dogwoods and some maples and oaks are produced by another type of pigment called anthocyanin, the pigment responsible for the color of cherries, grapes, apples and blueberries. Unlike chlorophyll and carotenoids, anthocyanins are not always present in the leaf but are produced in late summer when environmental signals occur. Anthocyanins also combine with carotenoids to produce the fiery red, orange, and bronze colors found in sumac, oaks, and dogwoods.

Red colors tend to be most intense when days are warm and sunny, but nights are cool–below 45º F. The color intensifies because more sugars are produced during warm, sunny days; cool night temperatures cause the sugars to remain in the leaves. Pigments are formed from these sugars, so the more sugar in the leaf, the more pigment, and, thus, more intense colors. Warm, rainy fall weather decreases the amount of sugar and pigment production. Warm nights cause what sugars that are made to move out of the leaves, so that leaf colors are muted.

Leaf color also can vary from tree to tree and even from one side of a tree to another. Leaves that are more exposed to the sun tend to show more red coloration while those in the shade turn yellow. Stress such as drought, poor fertility, disease or insects may cause fall color to come on earlier, but usually results in less intense coloration, too. And stress or an abrupt hard freeze can cause leaves to drop before they have a chance to change color.

So far, weather conditions lead me to think this will be one of those not so showy fall color years. I hope I am proven wrong!

Cities and towns in the U.S. contain more than 130 million acres of forests. These forests vary extensively in size and locale. An urban forest can describe an urban park such as Central Park in New York City, NY, street trees, nature preserves, extensive gardens, or any trees collectively growing within a suburb, city, or town. Urban forestry is the name given to the care and maintenance of those ecosystem areas that remain after urbanization. Data from the 2010 census indicated more than 80% of Americans live in urban centers with a population increase greater than 12%. The population of Indiana represents only 2.1% of the nation. In the last 8 years, IN has had an influx of 200,000 people which represents a population increase of 3.0%!

Urban forests, which help filter air and water, control storm water runoff, help conserve energy and provide shade and animal habitat must be maintained. As our nation becomes more urbanized, appreciate those urban foresters working to ensure we have save urban forest spaces to enjoy. These precious resources add more than curb appeal and economic value, they improve our quality of life.

This past summer marked the first year of the Research and Extension Experiential Learning for Undergraduates (REEU) program at Purdue University. This program entitled “Diversity in Faces, Spaces and Places” was designed to increase visibility of underrepresented students and professionals in Natural Resource sciences disciplines and provide targeted mentorship to current underrepresented undergraduates.

During this PAID 8-week summer program, students were exposed to and participated in a plethora of activities such as: stream ecosystem health evaluation, mammalian tracking and trapping, reptile and amphibian habitat suitability studies, avian mist-netting, bat auditory identification and examination, and the role of genetics in the susceptibility of trees to disease. Students created posters of their research, gave oral presentations, and wrote a manuscript article on their chosen topic of study at the end of the program. Be a part of the fun next year!

Epizootic Hemorrhagic Disease (EHD) in deer

Deer that die from EHD are often found around water. This deer was found in August 2019 in Crawford County and was likely killed by EHD. Photo courtesy of Brody Wade.

Be on the watch for deer with EHD in Indiana
Recently, a white-tailed deer in Clarke County Indiana tested positive for Epizootic Hemorrhagic Disease (EHD), and potential EHD cases have been reported in 26 other Indiana counties. Here are a few things you should know about how EHD, how to spot it, and how to report it.

What is EHD and BTV?
Epizootic hemorrhagic disease (EHD) and bluetongue virus (BTV) are viral diseases, collectively called hemorrhagic diseases (HD), and are common in white-tailed deer. Both diseases are transmitted by biting midges often called “no-see-ums” or gnats. Neither disease is a human health issue, but they can cause significant mortality in white-tailed deer. Outbreaks of HD tend to impact deer populations locally, meaning an outbreak may occur in one part of a county but not in other parts.

When do EHD outbreaks occur?
EHD and BTV outbreaks often occur in late summer and early fall (August-September), especially in years with drought-like conditions. Drought causes water sources to shrink, which creates warm, shallow, and stagnant pockets of water creating ideal breeding habitat for the midges that transmit EHD. Deer also congregate in these areas to find water, which helps the midges pass the disease between infected and healthy deer. EHD outbreaks can last until a frost that kills the midges.

What are the signs of a deer with EHD?
Deer with EHD often appear weak, lethargic, and disoriented. Other signs of EHD in deer are ulcers in the mouth or on the tongue, swollen face, neck, or eyelids, and a bluish color to the tongue. Deer with EHD often search for water to combat the fever caused by the disease. EHD can be confirmed by testing blood and tissue (i.e., spleen) samples, but samples must be collected shortly after death.

Where am I likely to find a deer with EHD?
Because deer with EHD often seek out water to combat the resulting fever, deer killed by EHD are commonly found around water. If you have a stream, creek, river, or other source of water on your property, looking in the vicinity of those areas can help you locate deer that have succumb to EHD.

What do I do if I find a deer I think has EHD?
If you come across a sick or dead deer that you think has EHD you can report it through an online reporting system run by the Indiana DNR. Here is a link to the reporting system: Report a Dead or Sick Deer.

Can deer survive an EHD outbreak?
Yes, some deer will survive EHD. While up to 90% of deer that contract EHD may die from the disease, the deer that survive build up antibodies to EHD, which may make them immune to future outbreaks. Additionally, does may pass the antibodies and immunity to their offspring.

Deer hooves, chronic HD

How can I tell if a deer I killed during hunting season has survived EHD?
If you kill a deer during the hunting season this year, pay attention to the hooves. Deer that survive an EHD outbreak often have indentions or cracks on their hooves (see picture).

Sloughing or splitting hooves on two or more feet of a deer taken during the fall hunting season are typlical of chronic HD. Photo used courtesy of the Southeastern Cooperative Wildlife Disease Study.

Are deer that have survived EHD safe to eat?
Yes, deer that have survived EHD are safe to eat.

One of the most dangerous pests to trees is a human, especially with equipment.  tree injury from equipmentInjuries to trees caused by a lawn mower or weed trimmer can seriously threaten a tree’s health.

Additionally, damage to the bark layer of trees causes a long-term liability by creating a wound which leads to a defect, becoming an unsafe tree.

The site of injury is usually the root flare area, where the tree meets the turf and gets in the path of the mower or trimmer.  The bark on a tree acts to protect a very important transport system called the cambium layer.

mower injury on tree

This is where specialized tubes are located which move nutrients and water between the roots and the leaves. Bark layers can vary in thickness on different tree species.  It can be more than an inch in thickness or less than 1/16 of an inch on young, smooth-barked trees such as maples and birch trees.  This isn’t much protection against string trimmers and mowing equipment, especially the young trees.

Any type of damage or removal of the bark and the transport system can result in long-term damage.  Damage, which extends completely around the base of the tree called girdling, will result in ultimate death in a short time.

weed eater injury on tree

Tree wounds are serious when it comes to tree health. The wounded area is an opportunity for other insects and diseases to enter the tree that causes further damage. Trees can be completely killed from an attack following injuries. Fungi becomes active on the wound surface, causing structural defects from the decay.  This weakens the tree or it eventually dies, creating a risk tree to people around it.

Newly planted, young trees need all the help we can provide to become established in the landscape and these trees are often the most commonly and seriously affected by maintenance equipment.  However, injury can be avoided easily and at very low cost with these suggestions.

  1. tree with mulch at baseThe removal of turf or prevention of grass and weeds from growing at the base of the tree are low-tech solutions to eliminate a serious problem. Spraying herbicides to eliminate vegetation around the base of the tree can decrease mowing maintenance costs. Be sure to use care when applying herbicides around trees.
  2. A 2-3” layer of mulch on the root zone of the tree provides an attractive and healthy environment for the tree to grow. Additionally, it provides a visual cue to keep equipment away from the tree.
  3. Also, trunk guards and similar devices can add an additional measure of protection for the tree. Using white, expanding tree guards can help improve the trees ability to withstand equipment contact, but also help to reduce winter injury.

Trees are a major asset to your property and important to our environment.  Protect our trees and preserve these valuable assets by staying away from tree trunks with any mowing or weed trimming equipment.  The damage lasts and it cannot be repaired and often results in losing your tree.

Purdue Landscape Report: When was the last time you really looked at your trees?  It’s all too easy to just trees, grasslandsenjoy their cool shade and the sound of their leaves, but if you don’t know what to look for you could miss deadly diseases or dastardly demons lurking in their leaves and branches. A quick check can help you stop a problem before it kills your tree or your local forest!

National Tree Check Month is the perfect time to make sure your tree is in tip-top shape! Our checklist will help you spot early warning signs of native pests and pathogens and invasive pests like Asian longhorned beetlespotted lanternfly, and sudden oak death. You can stop invasive pests in their tracks by reporting them if you see them.

Is your tree healthy and normal?
Start by making sure you know the type of tree you have. Is it a deciduous tree like an oak or maple? Or is it an evergreen that like a spruce or a pine? Don’t worry about exactly what species it is. It’s enough for you to have a general sense of what the tree should look like when it’s healthy.

Check the leaves

  • Are the leaves yellow, red or brown?
  • Are they spotted or discolored?
  • Do the leaves look distorted or disfigured?
  • Is there a sticky liquid on the leaves?
  • Do the leaves appear wet, or give off a foul odor?
  • Are leaves missing?
  • Are parts of the leaves chewed?

Check the trunk and branches

  • Are there holes or splits in the trunk or branches?
  • Is the bark peeling from a tree that shouldn’t shed its bark?
  • Are there tunnels or unusual patterns under the bark?
  • Is there sawdust on or under the tree?
  • Is there sap oozing down the tree?
  • Does the sap have a bad odor?
  • Do sticky drops fall on you when you stand under the tree? You might have spotted lanternfly. Please report it right away!

Now what? If you answered YES to any of the questions above, there’s a good chance something is wrong. To decide if and how you should treat or report the problem, you’ll need to have a tentative diagnosis. Luckily, there are many ways to get one!

Know the tree species? Use the Purdue Tree Doctor to get a diagnosis and a recommendation on whether treating or reporting is needed.  This app allows you to flip through photos of problem plagued leaves, branches and trunks to help you rapidly identify the problem.  If you have an invasive pest, it will guide you how to report it.

Don’t know the tree species and still need help? Reach out to local experts. We’re happy to help!

Confused but think something is TERRIBLY WRONG?  Contact Purdue’s Exotic Forest Pest Educatorreport online, or call 1-866-NOEXOTIC.
