The Silver Orb spider’s botanical name is leucage dromedaria. It gets its common name from its bright silver abdomen. It is a member of the suborder of spiders called araneomorphs. This means that the fangs have a side-to-side operation. It is the size of a 20c piece and it hangs upside down in its web.

Silver orb spiders live Australia-wide and in the North Island of New Zealand. It builds its web close to the ground in grassy bush land areas.
Silver orb spiders eat flies, moths, bugs and beetles.
The web of the silver orb spider is a circular spoked web with a tidy spiral. The New Zealand variety sends spokes to the ground but the Australian resident does not. The web hangs horizontally and the spider hangs in the centre underneath it. This makes the spider difficult for its predators to see because the underside of the spider is green-brown, the legs are light green and the head is dark green. From under the web, the spider is well camouflaged because the silver abdomen blends into the skyscape.
After breeding, the female kills the male and eats it. The baby spiders stay at the edge of the web.
Silver orb spiders are not venomous! No bites have been recorded.
