Spiny Oakworm Moth
A medium-sized saturniid with rich orange-brown wings bearing a small white discal spot. Males are darker and smaller than females, with more feathery antennae.
Did You Know?
The spiny oakworm caterpillar is covered in sharp branching spines that can cause a mild irritation to the skin when handled carelessly.
Arctic Woolly Bear Caterpillar Moth
A close relative of the Greenland woolly bear, this moth has pale gray wings and a densely furred body. The caterpillar is covered in long dark hairs and freezes solid each winter. Adults have reduced mouthparts.
Did You Know?
This moth's caterpillar is parasitized at very high rates by ichneumon wasps, which may extend its already decade-long development even further.
