Agelenidae Genera
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] |
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 ...

Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the ...

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

Sometimes referred to as Eurasian grass spiders, they trap their prey by weaving entangling non-sticky funnel webs. They are limited to the Old world, ...''.

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.

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species dive ... (spiders) has the seventh-most species of all orders.
