Compared to bees, what is characteristic of the wasp integument?
Answer
It tends to be much less hairy, appearing smoother or glossier.
A key morphological distinction used to differentiate wasps from bees involves the body's outer covering, or integument. Bees have evolved to be covered with dense, often branched hairs which are functionally necessary for gathering and transporting pollen grains from flowers. In contrast, wasps generally lack this heavy hair covering; they appear much smoother, glossier, or more polished in texture. While some solitary wasp species may possess fine hairs, the prominent, fuzzy appearance typical of familiar bees like bumblebees is characteristically absent in the majority of common wasp species, reflecting their different primary ecological roles.
