Elm Leaf Beetle
A yellowish-green beetle with dark stripes along its elytra. Both adults and larvae feed on elm leaves, sometimes causing severe defoliation.
Did You Know?
Heavy infestations can strip an elm tree of nearly all its leaves in a single season.
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.
