Hangingflies, Hanging scorpionflies
Bittacidae is a family of scorpionflies commonly known as hangingflies or hanging scorpionflies. Adults are characterized by their distinctive hanging posture, grasping vegetation with their forelegs while using their raptorial hindlegs to capture prey. The family exhibits notable sexual behavior including nuptial prey gift exchange, where males present captured prey to females during courtship. Bittacidae has a cosmopolitan distribution with significant diversity in Australia, where the genus Harpobittacus represents the largest radiation. The family has been subject to extensive taxonomic study, particularly in the Afrotropics where Dr. Jason Londt described more species than any other author.
