Numbers

6 spp. in a single genus in our area, ~280 spp. in 11 genera of 3 subfamilies total(1)

Size

1.5-5.0 mm(2)

worldwide(1)

Habitat

Found in the fur of bats

Food

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.
