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.
Dusty Cicada
A medium to large cicada with a dusty gray-brown body and translucent wings bearing dark venation. It is one of the more commonly encountered cicadas in Madagascar.
Did You Know?
Its species name 'pulverea' means dusty, referring to the fine powdery coating on its body that helps regulate temperature.
