Glossosomatidae
The Glossosomatidae are a family of the class Insecta and order Trichoptera.The family contains 23 genera in three subfamilies. In the US alone, there are 76 spp. in 6 different genera.Merritt, RW, Cummins, KW, Berg MB. (2008). An Introduction to the Aquatic Insects of North America, 4th ed. pp. 443, 446-448, 451-454, 460, 470-473 Glossosomatids, commonly known as the Tortoise or Saddle-Case Makers, and are worldwide in distribution. The common names were derived from the domed shaped cases created by the larvae. The first species was described by John Curtis in 1843, but the family wasn't created until 1891 by HDJ Wallengren. Morphology Larvae: Glossosomatid larvae have membranous meso- and metanotums (or if they do have sclerites, never more than half of the notum). They do not possess a prosternal horn. Their 9th abdominal segment has a sclerite. In addition, Glossosomatids tend to have short anal prolegs complete with accessory hooks. Adults: Glossosomatid adults tend to ...

Insects Described In 1941
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
