Brachycybe lecontii
Feather Millipede
Brachycybe lecontii is a small, eyeless, pink-colored millipede endemic to the eastern United States. It is one of the few known social millipedes, forming multi-generational colonies and distinctive "pinwheel" aggregations during feeding. Males exclusively provide paternal care of eggs during a 3–4 week incubation period; egg survival depends entirely on this care. The species is obligately fungivorous, feeding on diverse fungi, and possesses specialized cuticular structures possibly adapted for mycophagy.
