Bornean Flat Stag Beetle
A medium-sized, very flat stag beetle with a glossy dark reddish-brown body perfectly adapted for living in thin spaces under bark. The mandibles are short but wide and strongly toothed.
Did You Know?
Its body is so flat that it can fit into gaps as thin as a few millimeters, making it nearly impossible for predators to extract.
Larger Grain Borer
A devastating pest of stored maize and dried cassava in Africa. It can cause grain weight losses exceeding 30% in untreated stores.
Did You Know?
A predatory beetle, Teretrius nigrescens, was introduced to Africa as a biological control agent against it.
