About the Trapdoor Spiders

Trapdoor spider is a common name given to several families of spiders that belong to the Idiopidae, Actinopodidae, Ctenizidae, Migidae and Cyrtaucheniidae groups.

Most of these spiders build burrows in the ground and a silken-hinged door at their entrance. Then, they open the door to grab the passing insect quickly. While most trapdoor species can make a special door at their burrow’s entrance, some don’t, but they are still called trapdoor spiders.

This is because the doors they create are highly camouflaged and cannot be detected until they open.

Their short, blunt spinnerets and small double spur halfway along their first leg help them easily move through the soil. Brown Trapdoor spiders are typically a dull brown colour with paler gold hairs on their carapace, as well as pale bars across their abdomen and eyes arranged in two compact rows.

Sigillate Trapdoor Spiders have a strongly arched glossy carapace along with 4 to 6 hairless spots on the abdomen and eyes arranged in three rows. These small creatures are fascinating to observe or learn about, making them a popular subject for study.

Misgolas group spiders are spread across eastern Australia. They can be found in coastal and highland regions of New South Wales and Victoria. As far as the brown trapdoor spiders are concerned, they are often found near Sydney.

Feeding and Diet

Trapdoor spiders have an interesting hunting strategy – they wait inside the burrows they construct, leaping out to grab any unsuspecting insect that passes nearby. Once their prey is within reach, they latch on firmly with their fangs and drag it back into the safety of their burrow.

While many kinds of insects are targeted by these efficient predators, the most commonly caught prey items are crickets, moths, beetles, and grasshoppers. It’s remarkable that such a small spider has perfected its hunting strategy until it can catch such large food items.

Breeding Behaviours

Mature male spiders wander in search of a mate during humid weather. Once they find a mate, they enter the female burrow for mating. Female trapdoors can lay eggs several months after mating, protecting them within their burrows. Once hatched, the juveniles stay for several months before dispersing on the ground to create their tiny burrows. As the spider grows, they widen its burrow.

Danger to Humans

Many times, brown trapdoor spiders are mistaken for funnel-web spiders. However, the bite of a trapdoor spider isn’t as dangerous as a funnel-web spider. If a trapdoor or sigillate bites you, you may only experience local pain and swelling.
