Slender Groundhopper

A small, fully-winged pygmy grasshopper found near water in marshy and boggy habitats across the Northern Hemisphere. Unlike many groundhoppers, it can fly well and readily colonizes new wetland sites.

💡

Did You Know?

It can swim and even submerge briefly to escape predators, unusual behavior for a grasshopper.

Pale Morning Dun

A small pale yellowish mayfly that hatches in large numbers on western North American streams during late spring. It is a crucial food source for trout.

💡

Did You Know?

Pale morning duns often hatch in such dense swarms that trout become highly selective, ignoring all but perfect imitations.
