What type of antennae structure is commonly observed in social wasps like yellowjackets and hornets?

Answer

Relatively short, elbowed antennae

The antennae are vital chemosensory organs used by wasps to detect crucial environmental cues, including the location of food sources, the presence of potential mates, or warnings about approaching danger. While the exact structure can vary across the vast diversity of wasp species, social wasps, such as the commonly observed yellowjackets and hornets, typically exhibit a distinct configuration. Their antennae are generally characterized as being relatively short in overall length and possessing an elbowed or bent shape. This structure is efficient for the short-range chemical analysis required during close proximity tasks like nest maintenance, foraging within dense foliage, or close social interaction within the colony structure.
