Agelenopsis
''Agelenopsis'', commonly known as the American grass spiders, is a genus of funnel weavers first described by C.G. Giebel in 1869. They weave sheet webs that have a funnel shelter on one edge. The web is not sticky, but these spiders make up for that shortcoming by running very rapidly. The larger specimens (depending on species) can grow to about 19 mm in body length. They may be recognized by the arrangement of their eight eyes into three rows. The top row has two eyes, the middle row has four eyes, and the bottom row has two eyes (spaced wider than the ones on the top row). They have two prominent hind spinnerets, somewhat indistinct bands on their legs, and two dark bands running down either side of the cephalothorax. Name The genus name is a combination of ''Agelena'' (Eurasian grass spiders), a genus of similar spiders, and Greek ''-opsis'' "to look like". They are harmless spiders. Although most spiders use their webs to catch prey, the grass spider's web lacks adhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agelenopsis Pennsylvanica
''Agelenopsis pennsylvanica'', commonly known as the Pennsylvania funnel-web spider or the Pennsylvania grass spider, is a species of spider in the family Agelenidae. The common name comes from the place that it was described, Pennsylvania, and the funnel shape of its web. Its closest relative is ''Agelenopsis potteri''. ''Agelenopsis pennsylvanica'' lives primarily as a solitary spider across the United States, having been found in at least 21 different states. It is an ambush predator, sitting and waiting for prey in its funnel-shaped web. In this species, the female commonly sexual cannibalism, cannibalizes the male during mating. This small species has been used to study pre-copulatory cannibalism, boldness, aggressive foraging behavior, and the influence of microbes in the reproductive cycle and mating behavior. Description Coloring The coloration of ''A. pennsylvanica'' is more visible in its Glossary of spider terms#carapace, carapace. The Glossary of spider terms#carap ...

Agelenopsis Aperta
''Agelenopsis aperta'', also known as the desert grass spider or funnel-web spider, is a species of spider belonging to the family Agelenidae and the genus ''Agelenopsis''. It is found in dry and arid regions across the southern United States and into northwestern Mexico. Their body is about 13–18 mm long and they have relatively long legs in order to run after their prey. Desert grass spiders can withstand very low temperatures even though they do not Cold hardening, cold harden. It constructs the characteristic funnel-shaped webs in crevices where the funnel will fit, where they wait in the tube for prey which they can run after using their long legs. They often hunt for their prey at night. ''A. aperta'' is known for its territoriality and will fight intruders to protect their space. ''A. aperta'' are mainly monogamous, and the male performs an elaborate courtship ritual that involves swaying his abdomen and releasing pheromones. The male's pheromones induce a cataplec ...

Agelenopsis Emertoni
''Agelenopsis emertoni'' is a species of funnel weaver in the family of spiders known as Agelenidae The Agelenidae are a large family of spiders in the suborder Araneomorphae.

It is found in the United States. The spider was named to honour arachnologist James H. Emerton. ''A. emertoni'' is distinguished from other ''Agelenopsis'' species in the genus by the male's loosely coiling embolus making more than one full circle, and a claw-like conductor tip. These features are sclerites of the male sex organ which is used to inseminate the female. The female has a distinctive conducting tube in her genitalia. The male can be between 6 and 13mm. Distribution is in the following states of the USA: Arkansas, Colorado, Florida, Georgia, Louisiana, Massachusetts, Mississippi, Missouri, New Jersey, New York, North C ...

Araneomorph Funnel-web Spider
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus ''Agelenopsis''. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (''Eratigena agrestis'') may be medically significant, and some evidence suggests it might cause necrotic lesions, but the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver. Description The body length of the smallest Agelenidae spiders are about , excluding the legs, while the larger species grow to long. Some exceptionally large species, such as ''Eratigena atrica'', may reach in total leg span. Agelenids have eight eyes in two horizontal rows of four. Their cephalothoraces narrow somewhat towards the front where the eyes are. Their abdomens are more or less oval, usually patterned with two rows of lines and spots. Some species have longitudinal lines on the dorsal surface of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
