Dwarf Sheet Spider

	Dwarf Sheet Spider Dwarf sheet spiders (Hahniidae) is a family of araneomorph spiders, first described by Philipp Bertkau in 1878. Their bodies are about long, and they build extremely delicate webs in the form of a sheet. Unlike many spiders the web does not lead to a retreat. The silk used in these webs is so fine that they are difficult to spot unless they are coated with dew. They greatly favor locations near water or near moss, and are often found in leaf litter and detritus or on the leaves of shrubs and trees. Description They are characterized by the arrangement of their six spinnerets in a transverse row. The last segment of the outer spinnerets is quite long and stands out above all the others. Distribution Hahniidae are a worldwide family. The genera of the Northern Hemisphere and Africa tend to differ in their genital structures from those of the Southern Hemisphere. Very few species have been described from southeast Asia, although quite a number seems to be yet undescribed. Name The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
