Mud daubers have a unique appearance, which makes identification much easier. Paper wasps prefer suspended nests, often building them on porch ceilings and window and door frames. Paper wasps make their nests out of chewed wood and saliva, and unlike hornets and yellow jackets, these pests do not cover the combs with an outer shell. Completed nests usually have a distinctive umbrella shape.Īs you can see in this photo, the nests have hexagonal cells like a honeycomb. Once the pest matures, they leave the empty cells behind.Īlthough paper wasp nests start small, the pests build outward until the structure is between six and eight inches wide. As seen in these close-up pest photos, full cells contain eggs and developing larvae. They may also have solid sections of color, rather than stripes, on their hourglass-shaped bodies.Ī paper wasp nest can hold anywhere from 12 to 100 insects. Some are black and yellow, while others have a reddish or dark brown hue. Roughly twice the length of a yellow jacket, paper wasps are the largest species in the Mid-Atlantic. Some species build subterranean homes, and a nickel-sized hole in your yard or garden may indicate the entry point for an underground nest. Yellow jackets construct round, layered nests in wall voids or crawl spaces under houses. They are only slightly bigger than a house fly, and their smaller size allows them to enter buildings through gaps and crevices in building foundations or tears in screens. Only about three-quarters of an inch in length, yellow jackets are the tiniest wasps in the region. A series of spots and triangular marks give the queen of the colony the most distinctive look. Males have skinny black stripes, while females have thicker bands along their abdomens. Their coloring is similar to bees, but as these yellow jacket images show, their markings are quite different.

The black and yellow coloring, slim build, and narrow waists of yellow jackets mean they’re often mistaken for honey bees. Check out the following wasp photos to learn more about pest identification and the distinctive characteristics of these insects. Certain wasp species can be hostile and being able to recognize them on sight is helpful to avoid attacks. ![]() While they have some similarities, these two types of pests have much different temperaments. Yellow jackets are the smallest (and nastiest), mud daubers are a little larger, and paper wasps are the biggest of the three. For example, you can tell most common Mid-Atlantic wasps apart by their size. However, each species has its own distinct appearance to distinguish them from other stinging insects. These wasps are beneficial to gardeners for the caterpillars they consume and as pollinators because the adults eat nectar and pollen.All wasps have six legs, two antennae, and pinched midsections. The Four-Toothed Mason Wasp has a white band at the upper end of the abdomen, while the Bald-Faced Hornet has white bands near the stinger. However, at first glance it does look a lot like the Bald-Faced Hornet, which is a colony (social) wasp that can be aggressive. While the female can sting, the male can only stab, but this wasp is not aggressive and seldom stings people. The female lays about 20 eggs, and there are two generations per year at least in their southern range. Wintering is hard on the larvae because they do not make a cocoon. Naturalists are not sure why, but it might be to provide insulation or to fool would be parasites. She seals the entrance with mud, leaves an air space, and seals it again. She can decide whether to lay a male or a female egg, and she lays the male egg closer to the entrance because it matures sooner. The female fills the chamber with one of her eggs and multiple (sometimes approaching 20) caterpillars that she has paralyzed to sustain the larva. ![]() She has also been observed evicting residents of an occupied chamber. ![]() The Four-Toothed Mason Wasp (Monobia Quadridens), a solitary wasp, likes to use unoccupied holes or nesting chambers made by various other insects, or she will make her own tunnel in dirt or wood.
