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.
Common Moth Fly
A tiny grayish moth fly with broad, hairy wings giving it a distinctly moth-like appearance. Its wings are held flat over the body at rest, and it runs in short hops when disturbed.
Did You Know?
Moth flies are important components of sewage treatment trickling filter beds where their larvae help break down waste.
