Agelena
Agelena is a genus of agelenid spiders first described by Charles Athanase Walckenaer in 1805. 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, occurring from Africa to Japan. Many species have been moved to other genera, particularly to Allagelena, Benoitia and Mistaria.

Agelena es un género de arañas araneomorfas que tejen telarañas de una gran superficie, en forma de embudo, en el fondo del cual acecha la araña a la espera de atrapar a sus presas. El género está limitado al Viejo Mundo, apareciendo desde África y Europa hasta Japón. En la península ibérica las dos especies más representativas de este género son Agelena labyrinthica y Agelena gracilens. En las islas Canarias encontramos varios endemismos como Agelena canariensis, Agelena gomerensis, Agelena gonzalezi y Agelena tenerifensis.

Agelena is a genus of agelenid spiders first described by Charles Athanase Walckenaer in 1805. 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, occurring from Africa to Japan. Many species have been moved to other genera, particularly to Allagelena, Benoitia and Mistaria.
==Life style== Agelena constructs a typical non-sticky funnel-web that features a flat open sheet-like area. The webs are usually positioned close to the soil surface within low vegetation. The capture web consists of a flat, slightly concave, non-adhesive silk sheet that measures 40-60 cm wide and is composed of a mesh of silken threads suspended by oblique and vertical threads. This sheet is laid over the ground or any horizontal area and is usually clearly visible in the early morning when it becomes covered with dewdrops. The web typically remains in the same location and is repaired and enlarged as the spider grows.
