Hyemerus tripartitus: A Hidden Jewel in European Ball CTENOCHORIDA – Insights from Fauna Europaea (2023) Freshwater entomology reveals vital clues about insect biodiversity and ecosystem health—and few species in Central and Eastern Europe capture the intricate dynamics of aquatic habitats like Hyemerus tripartitus. Recent updates from Fauna Europaea (2023) spotlight this distinct caddisfly, shedding new light on its ecology, distribution, and conservation significance. This article explores Hyemerus tripartitus based on the latest taxonomic and ecological data available through Fauna Europaea, offering key insights for researchers, conservationists, and nature enthusiasts alike. ### Taxonomy and Identification Hyemerus tripartitus belongs to the family Diperobitidae (formerly classified under Hydroporidae), a group of small aquatic insects within the order Trichoptera. Known colloquially as the “three-parted” caddisfly, its name derives from the three clearly defined dark markings visible on its thorax and abdomen, a key diagnostic feature. Adult males typically measure 6–8 mm; females are slightly larger, reflecting typical sexual dimorphism in caddisflies. larvae remain submerged in riffle zones of clean, well-oxygenated streams, constructing portable cases from silk and environmental debris—a hallmark of many hydroporid species.
