A common spider, often found in urban environments (homes and backyards) is the Redback Spider (Latrodectus hasselti). This species of spider are found throughout Australia and is highly venomous.
The adult female Redback Spider has an almost spherical black body with a prominent red stripe-shaped mark, on the upper side of her abdomen and an hourglass shaped red mark on the underside. The colour can appear different (especially under different lighting) from a brown-red to red-orange colour.
The female spider have a body length of about 10 millimetres, whilst the male is smaller, being only 3–4 mm in length. In the following photography, you can see the larger female (with the prey) and in the background is the male Redback Spider.
The colour stripe and body of the Redback Spider can appear variable. This is usually found in the immature spiders, which can be pale brown in colour (especially when a spider has moulted).
The Redback Spider can often be found in an untidy web, often located in a sheltered location (in garden sheds, outdoor dunnies, under tables and chairs). They prey on a variety of insects, spiders and small vertebrates that are ensnared in its web. They have been documented catching lizards and small snakes. They incapacitate their prey by injecting a complex venom through its two fangs when it bites, then wrapping the prey in silk.
