Winter Stonefly
A dark-colored stonefly that emerges during winter months when few other aquatic insects are active. Adults can be found walking on snow near streams.
Did You Know?
Winter stoneflies are among the very few insects that emerge as adults during the coldest months of the year.
Weighted Casemaker
A caddisfly that attaches heavy ballast stones to the sides of its case for stability. Larvae are found in fast-flowing stony streams.
Did You Know?
The ballast stones can weigh several times more than the larva itself, preventing displacement by floods.
