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.
Giant Caddisfly
The largest European caddisfly with mottled brown-and-cream wings spanning up to 60 mm. Its larvae build portable cases from spirally arranged plant fragments.
Did You Know?
Giant caddisfly larvae construct their cases in a beautiful spiral pattern from carefully cut pieces of leaves and stems.
