Agelenidae
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 cephalothorax, 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 dorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Giant House Spider
The giant house spider has been treated as either one species, under the name ''Eratigena atrica'', or as three species, ''E. atrica'', '' E. duellica'' and '' E. saeva''. , the three species view was accepted by the World Spider Catalog. They are among the largest spiders of Central and Northern Europe. They were previously placed in the genus ''Tegenaria''. In 2013, they were moved to the new genus ''Eratigena'' as the single species ''Eratigena atrica''. In 2018, the three separate species were restored. The bite of these species does not pose a threat to humans or pets, and they are generally reluctant to bite, preferring instead to hide or escape. Description The two sexes do not differ in coloration or markings. Its coloration is mainly dark brown. On its sternum is a lighter marking, with three light spots on each side that form an arrow-like shape pointing toward the head of the spider. The opisthosoma features a lighter middle line with six "spots" on each side. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Eratigena Agrestis
The hobo spider (''Eratigena agrestis'', formerly ''Tegenaria agrestis'') is a member of the family of spiders known colloquially as funnel web spiders, but not to be confused with the Australian funnel-web spider. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. Hobo spiders sometimes build their webs in or around human habitations. The hobo spider lays its eggs in September and they hatch during late spring. After the male hobo spider mates it dies. Taxonomy The species was first described in 1802 by naturalist Charles Athanase Walckenaer as ''Aranea agrestis'', in reference to its western European habitat in fields, woods, and under rocks. In 1841, Walckenaer transferred the species to the genus ''Tegenaria''. In 2013, ''Tegenaria'' was split up, and the hobo spider was transferred to a new genus ''Eratigena'', an anagram of ''Tegenaria''. Identification Spiders, in ...

Acutipetala
''Acutipetala'' is a small genus of southeast Asian funnel weavers native to the evergreen forests of northern Thailand. They are medium-sized spiders, to long, and are distinguished by the distinctive appearance of several genital structures, including the embolus and the median apophysis of the male pedipalp. The eyes are in two rows, both of which are strongly curved forward. The genus was first described by P. Dankittipakul and Z. S. Zhang in 2008, and it contains only two species: '' A. donglini'' and '' A. octoginta''. The name is a combination of the Latin " acutus", meaning "sharp", and the Greek " petalon" (), in reference to the sharp, flower petal shape of the medial apophysis of the male pedipalp.

''Allagelena'' is a genus of Asian funnel weavers first described by Z. S. Zhang, Ming-Sheng Zhu & D. X. Song in 2006.
