Luprops tristis
The Mupli beetle, Luprops tristis, is a plant detritus eating darkling beetle found in parts of India. The adult beetle is black and around 8 millimetres (0.31 in) long.

Description
Luprops tristis goes through five larval instar stages and a pupal stage before the adult stage. The adult beetle is colored black. There is very little sexual dimorphism, and males and females overlap in size. After a month of active feeding in the adult form, they go into a lengthy dormant period in a suitable undisturbed dark location in response to the first summer rains before emerging again to feed and reproduce.
