What is a signature characteristic of the male mosquito?

• A. Bushy antennae and long palpi
• B. Long proboscis
• C. Bright wing patterns
• D. Dark body color

Answer: (A)

Male mosquitoes are identified by their bushy, plumose antennae, which are used to detect the wingbeat frequencies of females during mating. This feathery look is the most recognizable and consistent cue for distinguishing males in the field. The combination with longer palps is often noted as part of their morphology, reinforcing that this species group has more elaborate sensory appendages. In contrast, females carry a long proboscis for blood-feeding, so a long proboscis is not a male trait. Wing patterns and body color can vary a lot between species and aren’t reliable indicators of sex. So the signature feature—very bushy antennae—along with the associated palpal trait—best identifies the male mosquito.
