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.
Eastern Weighted Casemaker
A caddisfly of clean European streams that builds mineral cases with large lateral ballast stones. Larvae scrape algae from rock surfaces in moderate current.
Did You Know?
The lateral ballast stones are so precisely placed they appear to be glued on by hand.
