Sand-Case Caddisfly
A caddisfly whose larvae build smooth, curved cases entirely from fine sand grains cemented with silk. Adults are dark with hairy wings.
Did You Know?
The curved sand-grain cases built by these larvae are so precisely constructed they resemble tiny miniature architectural works.
Marbled Sedge
A net-spinning caddisfly with distinctly marbled wing patterns. It is common in larger European rivers and is tolerant of moderate levels of organic enrichment.
Did You Know?
Marbled sedge larvae are territorial and will aggressively defend their net-spinning sites from rivals.
