Yellowjackets
Vespula spp., Dolichovespula spp.
Size: ½ inch long

Where/When: Wasp nests are commonly found on horizontal surfaces on buildings and trees and shrubs as well as in the ground. They are uncommonly found on flowers. Active from spring to fall.

Significance: They can be a problem when they nest in or near gardens because of their ability to sting. Some species can be attracted to gardens during late summer and fall to feed on injured or overripe apples, grapes, and raspberries.
