Vespula vidua
widow yellowjacket, long yellowjacket
Vespula vidua is a species of social wasp in the family Vespidae, commonly known as the widow yellowjacket or long yellowjacket. It is native to North America and exhibits typical yellowjacket biology with annual colonies founded by overwintering queens. Unlike some urban-adapted yellowjacket species, V. vidua is strictly predatory and does not scavenge at human food sources. The species is known to be a host for the facultative social parasite Vespula squamosa (Southern Yellowjacket), which can usurp its nests.
