Vespula acadica

Description

Vespula acadica, also known as the Forest Yellowjacket, is a North American species of eusocial wasp which is part of the "rufa" group within the genus Vespula. It is a black and yellow wasp that is found in arboreal areas and builds its nests most often in decaying vegetation like logs, but has occasionally been found to build aerial nests. Due to its preference for forests V. acadica does not normally come into contact with humans; however, when colonies are disturbed, workers of this yellowjacket may be quite aggressive and persistent and sting repeatedly.
