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.
Spruce Gall Adelgid
A tiny woolly aphid-like insect that induces distinctive pineapple-shaped galls on Norway spruce twigs. The galls form when the insect's feeding causes abnormal growth of developing needles.
Did You Know?
The pineapple-shaped galls are formed by modified needles that swell and fuse together, creating chambers in which the adelgid nymphs develop protected from the environment.
