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.
Helvetian Ground Beetle
A cold-adapted ground beetle of high-altitude scree and moraines. It is active during short alpine summers near snowmelt areas.
Did You Know?
It can remain active at temperatures just above freezing.
