Blue-winged Rove Beetle
A handsome rove beetle with a metallic blue-green head and pronotum contrasting with brown elytra. It is found in wooded areas and is a capable flier attracted to lights at night.
Did You Know?
The metallic coloration of its head is produced by nanostructures in the cuticle that interfere with light, similar to how a soap bubble creates colors.
Long-Palped Crane Fly
A short-bodied crane fly whose predatory larvae inhabit gravel beds of clean streams. Larvae are active hunters among cobble interstices.
Did You Know?
Unlike most crane fly larvae, this species is an active predator rather than a detritivore.
