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 limbata is one of the most common web-weaving spider species in Japan.
