Arctopsyche grandis
netspinning caddisfly
Arctopsyche grandis is a species of netspinning caddisfly in the family Hydropsychidae, found in North America. Larvae construct silk nets to capture food in flowing water and complete their development in approximately one year. The species has been studied in Central Idaho streams where it reaches high population densities on rocky substrates.
Hydropsyche morosa
A net-spinning caddisfly species found in summer-warm rivers of southern Ontario. Has been observed to be bivoltine in lower river reaches where summer water temperatures exceed 24°C for extended periods. Larger-bodied than the sympatric Hydropsyche bronta, with which it shares habitat in the Credit and Humber river systems.
Hydropsyche walkeri
Hydropsyche walkeri is a species of net-spinning caddisfly in the family Hydropsychidae. Originally described by Betten and Mosely in 1940, it is currently treated as a synonym of Ceratopsyche walkeri. The species belongs to a diverse genus of aquatic insects whose larvae construct elaborate silk nets to capture food in flowing water. Like other hydropsychids, it is associated with freshwater lotic habitats.
Hydropsychinae
net-spinning caddisflies
Hydropsychinae is a subfamily of caddisflies (Trichoptera) within the family Hydropsychidae, commonly known as net-spinning caddisflies. Larvae construct fixed capture nets in flowing water to filter food particles. The subfamily is taxonomically diverse, with generic revisions documented in multiple regions including New Zealand and the Americas.
Hydropsychoidea
net-spinning caddisflies
Hydropsychoidea is a superfamily of caddisflies (order Trichoptera) first described by Curtis in 1835. The constituent families, particularly Hydropsychidae, are commonly known as net-spinning caddisflies due to the distinctive capture nets constructed by their larvae. These insects are predominantly aquatic in their immature stages and are among the most frequently observed caddisflies in stream environments worldwide.
Philopotamoidea
Philopotamoidea is a superfamily of caddisflies (order Trichoptera) comprising two families: Philopotamidae and Stenopsychidae. The superfamily is considered paraphyletic in current phylogenetic treatments. Members are aquatic insects with larval stages inhabiting freshwater environments. The group is recognized by morphological features of adult mouthparts and larval case construction.
Plectrocnemia
tube maker caddisflies
Plectrocnemia is a genus of tube maker caddisflies in the family Polycentropodidae comprising more than 120 described species. Larvae are aquatic predators that construct silken capture nets to intercept prey. The genus has been extensively studied for its larval silk production, vibration-mediated predatory behavior, and population genetics. Species occur across Europe and into western Asia, with detailed biological information available for several well-studied species including P. conspersa and P. brevis.
