Stenopsyche Marmorata
''Stenopsyche marmorata'' is a species of caddisfly The caddisflies (order Trichoptera) are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis ... found in Japan. The larvae live in fast-flowing streams and are harvested by Japanese fishermen for ''zazamushi'', a traditional dish made from a mixture of aquatic insect larvae cooked in soya sauce and sugar. This species is widely distributed in Japan, Sakhalin (Russia), the Korean Peninsula, northeastern China, and the Russian Primorsky Territory. The larvae spin silk nets in streams in which animal and plant matter are trapped and upon which they feed. The larvae grow longer than 2 cm and are the largest caddisflies in the region. In the Primorsky Krai, they constitute 77% of all the trichopteran biomass and 35% of all riverine benthic biomass. The larvae live amid musse ...

Caddisfly
The caddisflies (order Trichoptera) are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and Molecular phylogenetics, molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous insect wing, wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
