Most brown garden spiders are venomous but are not typically aggressive. Typically, female spiders are larger and more visible than males, but both spin intricate webs to catch flying insects. They usually have eight eyes and mouthparts called chelicerae. ![]() They have eight legs attached to their head and thorax (cephalothorax) part. Like all arachnids, a spider’s anatomy consists of a body divided into two segments-cephalothorax and abdomen.

Descriptions and pictures of eight-legged brown arachnids will help you identify common spiders in garden landscapes. This article is a guide to the types of brown garden spiders you can find in a front or backyard. For example, the brown recluse spider can bite, resulting in a painful inflamed patch as its venom destroys skin tissue. Identifying brown garden spiders is vital, as some can inflict a painful bite. Therefore, they help to control insect populations, reducing the need for chemical pesticides. The outdoor spiders weave intricate webs to capture pests like mosquitoes and flies.

Danger to humansįew bites by these spiders have been reported and when they have, symptoms have been minor, consisting of a red welt and localised hot feeling for a couple of hours. Despite the heavy appearance of their fangs, these spiders are reluctant to attack and timid when confronted. The males also have characteristic club-shaped palps and can look quite threatening when these are held aloft. Wandering males frequently enter houses at night, and their bright colours can cause alarm. The oval egg sacs have a papery texture, and hold about 50 eggs. In contrast, the females have rarely been observed far from the burrow. Male spotted ground spiders live a vagrant life hunting or searching for females they may be found in leaf litter, under logs or rocks, or even indoors wandering across the floor. Some species, like Habronestes bradleyi, are closely associated with ants. Some species build burrows in the ground or shallow depressions, and build a palisade (fort-like structure) of vertically arranged twigs or leaves around the entrance. Like many spiders, little is known about their biology. Spotted ground spiders don't build a snare, but hunt and ambush ground dwelling insects. They mingle with the ants in their nest in the early mornings, when the ants are sluggish, and carry off the weaker ants as prey. ![]() One species of Storena is an ant mimic, resembling the red meat ants, Iridomyrmex purpureus.
