Pale-bordered Field Cockroach
A small outdoor cockroach with a distinctive pale border around its dark pronotum. It is an active daytime flier unlike most cockroaches. It feeds on pollen and decomposing vegetation.
Did You Know?
Unlike most cockroaches, it is diurnal and can be seen actively flying in sunny fields during the day.
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.
