1Bdellinae is a of predatory mites in the Bdellidae. Members are active hunters of small arthropods and have been utilized as agents. The first complete ontogeny for the type Bdella muscorum was described in 2022, documenting morphological progression through five life stages.

Identification
Bdellinae can be distinguished from other snout mites by the progressive addition of setae through ontogeny: hypostomal setae increase from 2 pairs in larvae to 6 in ; aggenital setae from 0 to 11; genital setae from 0 to 8. Palpal basifemur setae and leg setae numbers also increase through successive instars.
