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.
Cicatricosus Scarab
A medium-sized dark roller with a rough, pitted exoskeleton that gives it a scarred appearance. It inhabits coastal sandy areas and constructs dung balls from rabbit and livestock dung. Active primarily at dusk.
Did You Know?
The rough texture of its exoskeleton helps it grip sand as it rolls dung balls across dune habitats.
