Lesser Swallow Prominent Moth
A white moth very similar to the Swallow Prominent but with a thinner dark wedge mark and a clear white hindwing. It is associated with birch rather than poplar.
Did You Know?
It can be reliably separated from its close relative only by examining the width of the forewing wedge mark.
Western Glacier Stonefly
A cold-specialist stonefly found only in glacier-fed streams in Glacier National Park. It is threatened by the retreat of mountain glaciers.
Did You Know?
It may become one of the first insects driven to extinction by climate change as glaciers disappear.
