If a worker yellowjacket is observed feeding on a piece of fallen fruit, what need is it primarily meeting?
Answer
Its immediate energy demands
When an adult worker yellowjacket feeds on a piece of fallen fruit, it is typically gathering juice to satisfy its own energy requirements right at that moment. This action stems from the adult need for carbohydrates to sustain their flying and foraging efforts. This behavior is distinct from gathering food for the colony; protein collection for the larvae involves hunting live prey. Observing an adult consume fruit juice is a direct visualization of their need for immediate sugar-based energy rather than provisioning the nest.
