All workers forage for honey, water, and fiber. In Hawaii, yellowjackets rob honey bee colonies through two major types of raids. Sometimes, yellowjackets enter and leave in a slow but steady traffic faced by opposition from honey bee workers. In the more common raid, yellowjackets enter individually and experience no apparent opposition. [15]

It is very similar to the common wasp (V. vulgaris), but unlike the common wasp, has three tiny black dots on the clypeus. To further complicate the issue this only applies to workers.

Schmidt set the sting of the Western honey bee at a pain level of 2 to be the anchoring value, basing his categorization of all other stings on it. [6] He has categorized a variety of wasps, bees, and ants into pain level 2, including yellowjackets, the Asiatic honey bee, the trap-jaw ant, and the bald-faced hornet. The duration of the pain of ...
