Family Nycteribiidae
Explanation of Names
Nycteribiidae Samouelle 1819
6 spp. in a single genus in our area, ~280 spp. in 11 genera of 3 subfamilies total(1)
1.5-5.0 mm(2)
Found in the fur of bats
Adults are obligate blood feeders on bats; larvae remain in mother until ready to pupate (as in other Pupipara)
Life Cycle
Females give birth to one (sometimes more) offspring in a process that resembles true viviparity. The fly leaves the host only to deposit the larvae in a safe place to pupate. Wingless (they can afford it because their hosts return to the same roost regularly.) --B. Zvolanek, FB comm.
