Deinopis subrufaCommon name: Common Net-casting Spider
Meaning of name: Deinopis is from the Greek words deinos, meaning fearful, and opis, meaning appearance. Subrufa is Latin for slightly reddish.
Distribution: Mostly reported from the east coast of Australia.
Description: This spider has a body length of approximately 25 millimetres.
Notes: Deinopis sp are net-casting spiders. The net which Deinopis makes is specially constructed so that it can be stretched. The spider hangs face-down over some place that some insects might walk, and it holds the net ready with its front legs. It then patiently waits for a critter to walk underneath it.
Once something wanders within range the whole net-cast-catch thing is over in less than a second. It lunges over the critter and wraps the sticky net over it. The prey is quickly overwhelmed.
We have seen this spider in January, June and December.
