Ogre-faced Net-casting SpiderNet Casting Deinopis
Belonging to the genus Deinopis, are the spiders known as the Ogre-faced Net-casting Spider. Their unique appearance have given them a variety of common names including Ogre-faced Spider, Gladiator Spider, Stick Spider, Web-throwing Spider and Net-casting Spider.
The Net-casting Spider are largish spiders, that are slow in movement. They have long body, up to 30 mm in length, with stick like legs. The body of the spiders tend to be light brown, to grey in colour. The genus Deinopis, with their eight eyes, two of which are enlarged and facing forward. The genus Menneus, has forward facing eyes that are less prominent.
In the following series of photos of the male Net-casting Spider, you can see the forward facing eyes, the chelicerae (the mouthparts of the Chelicerata) and the pedipalps (the second pair of appendages of chelicerates that are also used as modified copulatory organs for holding on to the female during mating). The mature male have large, prominent pedipalps.
They have a wide tropical and subtropical range, although if you look at the distribution map on iNaturalistAU, they have been recorded around Australia’s coastal region, especially down through Queensland, New South Wales, Victoria, South Australia and Tasmania. They are widely distributed through the forest habitats of south-eastern Australia.
The genus Deinopis is derived from the Greek deinos, meaning fearful, and opis, meaning appearance.
The amazing thing about the genus Deinopis spiders, are the way they catch their prey by creating and casting a net known as a cribellate web. Check out our page on the Net Casting Deinopis.
