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.

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.

Italian Locust

A medium-sized locust with pink hindwings found across southern Europe and Central Asia. It favors dry, warm habitats and can swarm during outbreaks.
