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.
Did You Know?
The flat, armored female looks so unlike a typical beetle that it was originally described as a separate species from the male.
Giant Amazonian Ground Beetle
A large Neotropical caterpillar hunter with dark elytra bearing rows of metallic pits. It is an important natural enemy of agricultural pest caterpillars in Central and South America.
Did You Know?
It is frequently attracted to lights at night and has been studied as a biological control agent for fall armyworm, a devastating pest of maize across the Americas.
