The female will lay her eggs several months after mating, and protects them within her burrow. The male usually escapes being eaten in order to mate with several females, before dying. Mating takes place within the female's burrow. Mature male Trapdoor Spiders wander during humid weather in search of a mate. Their eyes are arranged in three distinct rows.Īlso, as there are several families of Trapdoor Spiders, identification to species level can be difficult without a detailed key. Sigillate Trapdoor Spiders are brown spiders with a strongly arched glossy carapace and 4-6 hairless spots (sigillae) on top of the abdomen. Brown Trapdoor spider eyes are arranged in two compact rows. There are often pale bars across the abdomen. These spiders tend to be quite timid, although the male may rear up if threatened.īrown Trapdoor Spiders are dull brown spiders with a cover of paler gold hairs on carapace ('dusty appearance') which is usually weakly arched in side profile. Females are larger than males, and tend to be harder to identify to species level. Males usually have a small double spur halfway along their first leg. They include a wide variety of types, many of which are adapted to drier habitats. The Brown Trapdoor ( Arbanitis sp) and the Spotted Trapdoor ( Aganippe sp) spiders belong to the family Idiopidae. The common name covers several families of spiders, including the Idiopidae, Actinopodidae, Ctenizidae, Migidae and Cyrtaucheniidae. For those species that do, these highly camouflaged entrances are almost undetectable, unless the door is open. Most trapdoor spiders, but not all, are misleadingly named, as not all species make a door for their burrows.
