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.
