Forest Tent Caterpillar Moth
A widespread North American moth whose caterpillars defoliate vast areas of hardwood forest. Despite the name, they form silken mats rather than true tents.
Did You Know?
Outbreaks can defoliate millions of hectares of forest, though healthy trees usually recover with new leaves.
Snow Scorpionfly
A tiny wingless scorpionfly active in winter, walking on snow near mossy habitats. Its vestigial wings are reduced to hook-like structures used during mating.
Did You Know?
Snow scorpionflies are most active at temperatures near freezing and can sometimes be found by the hundreds walking across snow-covered moss.
