Hololena curta, commonly known as corner funnel weaver or funnel web spider, is a species of venomous spiders belonging to a family of Agelenidae.
It is native to Canada and the United States.[1]
This species and related species produce a venom that contains a group of insecticidal acylpolyamines, insecticidal peptide,[2] and a group of neurotoxins.[3]
Males have adapted to avoid sexual cannibalism by mating with virgin females, as both females and males can mate multiple times, but females become aggressive after having mated.[4]
