Foraging Patterns of Yellowjackets, Vespula pensylvanica, in an Artificial Flower Patch
Vespula pensylvanica, yellowjackets, were attracted to artificial flower patches, made repeated foraging trips, and returned on successive days. We ob- served the foraging patterns of Vespula pensylvanica in blue-yellow color-dimor- phic and clove-peppermint odor-dimorphic artificial flower patches, with variable sucrose molarities and volumes, as previously used to study honey bees. Yel- lowjackets foraged randomly in color-dimorphic patches regardless of reward volume or odor. When one morph provided 1.5 M sucrose, the other 2.5 M sucrose, vespulid wasps foraged randomly. When one morph provided 1.5 M sucrose, and the other flower morph 0.75 M sucrose, yellowjackets visited ran- domly but only drank the richer solution. In odor-dimorphic monochromic patches yellowjackets foraged randomly.
