Dindymus Explained

Dindymus is Old World genus of true bugs in the family Pyrrhocoridae. Records of occurrence include Africa, but most are in SE Asia and Australia.^[1]

Description

These bugs are often coloured red/orange and black; they may be confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head.
