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.
Cabbage Seed Weevil
A small grey weevil that is a major pest of oilseed rape. Larvae feed inside seed pods, consuming developing seeds. Causes significant economic losses across Europe.
Did You Know?
Entry holes made by egg-laying females also allow the larvae of the brassica pod midge to enter, compounding damage.
