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.
Parasitic Wood Wasp
A small, dark-bodied wasp-like insect with a flattened head and short antennae inserted below the eyes. It is among the most primitive parasitoid Hymenoptera.
Did You Know?
Orussidae are considered the evolutionary link between sawflies and parasitoid wasps, making them key to understanding Hymenoptera evolution.
