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.
Red Oak Borer
A large reddish-brown cerambycid that breeds in living red oaks across eastern North America. It has a strict two-year life cycle with synchronized adult emergence in odd-numbered years in some regions. Larvae bore into heartwood.
Did You Know?
Outbreaks of this beetle in the Ozarks during the early 2000s killed thousands of red oak trees across the region.
