Arctic Tussock Moth
A medium-sized moth with pale grayish-white wings in males and larger, more robust females. The caterpillar is strikingly hairy with tufted dark and pale hairs. It is found in northern heathlands and boreal forests.
Did You Know?
The caterpillar's dense coat of hairs acts as insulation, allowing it to bask in the sun and raise its body temperature for active feeding.
Limnephiloid Snail Caddis
A tiny caddisfly that builds a perfectly spiraled case from fine sand grains cemented with silk. Larvae scrape algae from rock surfaces in clear streams.
Did You Know?
The coiled case provides structural strength far exceeding that of a simple tube of the same material.
