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.
Elm Leafminer
A sawfly whose larvae mine between the upper and lower surfaces of elm leaves. Mines appear as blotchy brown patches on foliage.
Did You Know?
Each larva creates a single blotch mine that can expand to cover half the leaf.
