Herbert Holdsworth Ross
Herbert Holdsworth Ross (3 March 1908 – 2 November 1978) was a British-Canadian systematic entomologist. He was the author of an influential ''textbook of entomology'' first published in 1949. He worked on many insect groups but was widely recognized for his work on the Trichoptera. Ross was born to Jonathan and Jessie Holdsworth in Leeds. The family moved to Vancouver where Ross was educated. He graduated from the University of British Columbia in 1927 and then studied at the University of Illinois, Urbana-Champaign. receiving an MS in 1929 and a PhD in 1933.

Brachycentridae
Brachycentridae is a family of humpless casemaker caddisflies in the order Trichoptera. It is found in North America, Europe, and Asia. Georg Ulmer first described it in Germany in 1903 as a subfamily of Sericostomatidae.Ulmer, p. 18. The type genus for Brachycentridae is ''Brachycentrus'' J. Curtis, 1834. Distribution The family Brachycentridae contains at least 100 species in about 8 genera. The genera ''Adicrophelps'' and ''Amiocentrus'' are found near the Arctic circle. ''Doliocentrus'' and ''Eorbachycentrus'' are found in southeastern Siberia and Japan and Western North America respectively. Larvae Most species' larvae make cases using plant or rock material. Several others make it out of silk. A few species' larvae in ''Brachycentrus'' form cases in the water with hairs sticking out to absorb food from the water.Wiggins, p. 292. Genera These eight genera belong to the family Brachycentridae: * ''Adicrophleps'' Flint, 1965 * ''Amiocentrus'' Ross, 1938 * ''Baissoplectrum'' ...

Trichoptera
The caddisflies, or 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 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 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 of habitats such as streams, river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
