It contains only one species, Bombycites oeningensis, described from a fossil pupa by the Swiss geologist and naturalist Oswald Heer.
Pupa: "Much stouter (i.e. than that of Eurema hecabe, and the keel formed by the wing-cases much less pronounced. The normal colour is pale green with a yellow lateral line. We have never found it on any plant except Senna occidentalis. It habitually rests on the upperside along the midrib, like almost all Pierine larvae."
When the pupa is ready, it wiggles to the surface just prior to eclosion.
Varroa sensitive hygiene (VSH) is a behavioral trait of honey bees (Apis mellifera) in which bees detect and remove bee pupae that are infested by the parasitic mite Varroa destructor.
