About Campsicnemus insuetus
Campsicnemus insuetus is a small long-legged fly with striking modifications of the male middle leg, including a swollen tibial region and a projecting, hair-bearing structure.
Natural history and identification
Campsicnemus insuetus is a small long-legged fly with striking modifications of the male middle leg, including a swollen tibial region and a projecting, hair-bearing structure. Females lack these male secondary sexual characters. The type is from Nualolo Valley, and later material includes Mōhihi, Waiʻalae, and Alakaʻi localities. These features are useful for identification, but their presence alone does not demonstrate a particular courtship behavior or larval habitat.
Kauaʻi occurrence and evidence
Atlas occurrence category: Present. Evenhuis 2003 revision treats this species as part of the Kauaʻi Campsicnemus fauna; the paper states the Kauaʻi species are island-endemic.
