Description

Yellow Jacket, Eastern (ground-nesting yellow jacket): Vespula maculifrons, annual nests. In spring, a solitary queen emerges from hibernation. She builds a small nest using chewed wood pulp and raises the first generation of workers on her own. After they emerge, these workers collect food while the queen restricts herself to laying eggs. The larvae are fed pre-chewed insects caught by adults, while the adults feed on nectar and fruit pulp. The nest grows quickly and may contain several hundred to a few thousand workers by the end of the summer.
