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.

A conspicuous white moth with bold black spots and an orange-yellow band across the wings. It played a historic role in the discovery of sex-linked inheritance.
Did You Know?
Leonard Doncaster's experiments on this moth in 1906 provided early evidence for sex-linked genetics.
