Asian Cockroach
Nearly identical in appearance to the German cockroach but with very different behavior, as it lives outdoors and is strongly attracted to lights. It is an excellent flier.
Did You Know?
The Asian cockroach is so similar to the German cockroach that even experts sometimes need laboratory analysis to distinguish the two species.
Finger-net Caddisfly
A medium caddisfly with golden-brown wings. Larvae spin finger-shaped silken nets in fast-flowing water to capture ultrafine particles of organic matter.
Did You Know?
Its silk nets have an incredibly fine mesh, filtering particles as small as one micrometer.
