Nanosella
Nanosella is a genus of featherwing beetles (family Ptiliidae) described by Motschulsky in 1869. Members of this genus are among the smallest known beetles, with body lengths often measuring less than 1 mm. The genus belongs to the tribe Nanosellini, which contains some of the most miniaturized insects in the world. These beetles inhabit decaying organic matter where they feed on fungal spores and hyphae.

Feather-winged Beetles, Featherwing Beetles
Ptiliidae is a family of extremely small beetles containing the smallest known free-living, non-parasitoid insects. Members range from 0.3 to 4.0 mm in length, with the smallest species, Scydosella musawasensis, measuring only 0.325 mm. The family has a cosmopolitan distribution and is characterized by distinctive narrow, feathery hindwings that give the group its common name. Their minute size imposes unusual biological constraints, including the production of very large eggs relative to adult body size.
