Sydney Brown Trapdoor Spider

The Sydney Brown Trapdoor spider (Misgolas rapax) is found mainly around Sydney, Australia and is a trapdoor spider. This spider is often confused with the Sydney Funnel-web spider, which is one of the world’s most venomous spiders. The Sydney Brown Trapdoor spider is generally shy and retiring.

The Sydney Brown Trapdoor spider ranges from medium-to-large in size. The female spiders are .78 inches in length while the males are .87 inches in length. They are both chocolate brown though the male has a slender build. The male Sydney Brown Trapdoor spider also has discrete shaped palps, which are the appendages that are placed at the front of the head in between the first pair of legs.

Occasionally, if harassed inside its burrow, one individual spider will stand up and show its fangs, otherwise Sydney Brown Trapdoor spiders are generally retiring and shy. Though they spend most of their time inside their burrows at night, they wait for food in front of their burrows.

During humid weather mature males wander around in search of a mate. Mating takes place inside of the female’s burrow. Generally the male gets away before being eaten in order to mate with many females before dying. Inside the mother’s burrow is a cocoon which the eggs are kept in. After hatching, the baby spiders linger inside the burrow for a while until they ultimately leave and fend for themselves.

The Sydney Brown Trapdoors dig an open burrow, lined with silk in the ground. The burrows may reach 10 inches in depth and around 1 inch in width. Around the entrance brown trapdoors may be found strewn with silk trip-lines.

Many times the Sydney Brown Trapdoors are mistaken for funnel-webs. Swelling may occur, as well as minor pain, but the bite of Sydney Brown Trapdoors is not dangerous.
