Tan Spotted Sedge
A medium-sized caddisfly whose larvae construct net retreats in fast-flowing upland streams. Adults are tan with spotted wings.
Did You Know?
Larvae aggressively defend their net territories from neighboring caddisflies.
Arctic Springtail
A white, eyeless springtail that lives in soil and under stones in the High Arctic. It lacks a furcula and cannot jump. It survives extreme cold through cryoprotective dehydration, losing most of its body water before freezing.
Did You Know?
This springtail can survive temperatures down to minus 30 degrees Celsius by dehydrating itself until it contains almost no free water.
