In this edition of Wildlife Habitat Hint, Purdue wildlife extension specialist Jarred Brooke shares methods to control the invasive sericea lespedeza. This plant species, though was once used for erosion control and mineland reclamation, is too invasive and of little wildlife value.

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.

Purdue Landscape Report: Hot, dry summers are not that unusual in the Midwest, but 2020’s hot dry spell started considerably earlier than usual, before summer even officially began! To make it a triple whammy, the hard freeze in early May caused some landscape plants to burn up more stored carbohydrate reserves to produce a second round of foliage.
(Figure 1) US Drought Monitor
I’m sure I don’t have to point out that most of Indiana is currently experiencing abnormally hot, dry conditions. Although recent rains have brought relief to some areas, any respite is sure to be temporary. Seasonal thunderstorms may deluge some landscapes with water while other areas, even those close by, may stay fairly dry. Much of the area has experienced highs in the upper 80’s to over 90º F over the past month.
Leaf scorch on trees and shrubs, appearing as a browning along the edges of the leaves, is very common in dry summers. While minor cases of leaf scorch are not very harmful, prolonged lack of moisture can spell disaster for landscape plants.
Young and newly established plants are most susceptible to the dry conditions, but even established plants may reach a critical point during prolonged drought. If the heat and drought continue this summer, branch dieback, combined with eventual root death, will make plants more susceptible to winter injury. Plants that were already under stress from other factors may succumb to severely dry soils.
The intense heat makes it difficult for plants to keep up with water and cooling requirements, even in areas where moisture is adequate. One of the ways that plants cool themselves is through transpiration, which allows water to evaporate from the foliage. Plant leaves have pores called stomata that can open and close to allow water vapor and gas exchange with the environment. During extreme heat and/or drought, stomata will nearly close, thus reducing transpiration and exchange of carbon dioxide and oxygen. The end result is seen as wilting foliage and leaf scorch. But not so obvious is that reduced water uptake and gas exchange also leads to reduced production of carbohydrates through photosynthesis and reduced uptake of soil nutrients, having longer term impact on plant health.
There is still plenty of summer yet to get through to see the further challenges ahead. Meanwhile, we can mitigate some of the stress by watering landscape plants as needed where feasible.
