What specific sweet substance excreted by aphids provides carbohydrates for adult yellowjackets?
Answer
Honeydew
Honeydew is explicitly identified as one of the primary carbohydrate sources utilized by adult yellowjackets to meet their energy requirements for flight and foraging. Honeydew is defined in the context as the sweet substance excreted by aphids and other types of sap-sucking insects. When adults are observed feeding on fruit or probing flowers, they are seeking these simple sugars. The presence of honeydew offers an easily accessible sugar source that complements fallen fruit and nectar.
