lovelybugs: 1. Hairiest Insect Female Long Tailed Dance Fly (Rhamphomyia Longicauda) Female Dance Flies are the hairiest insects. They use their hairy legs to impress males. They don’t hunt for their own food at all, but rely on males to bring them protein-rich insects to eat when they mate. Before sunset, a swarm of 100 female Dance Flies wait for their mates, who bring them food, routinely mate with them and leave. Follow me for a new, interesting insect each day!
