Malaysian Trilobite Beetle
A bizarre beetle whose larviform females retain a flat, segmented larval appearance throughout life, resembling ancient trilobites. Males are small, winged, and conventionally beetle-shaped.

The flat, armored female looks so unlike a typical beetle that it was originally described as a separate species from the male.
Australian Diving Beetle
A large olive-green diving beetle found in freshwater habitats across Australia. It is one of the most commonly encountered large water beetles on the continent.
Did You Know?
During droughts it can fly long distances at night to find new water bodies.
