Family Theridiidae, Comb-Footed Spiders

They are commonly called Comb-Footed Spiders. Usually they build tangled webs under stones, between very close tree trunks, against fences or walls. 
 
 
The spiders in this family are usually small in size. The distinguishing feature of this family is the row of spines on the tip of the fourth legs, which are used to comb out wide swathes of silk to entangle their prey. Their eyes are in two rows of four.

This spider is mottled cream-brown and the legs are red-brown. More information can be found on this page.

Red Back Spider
wpe1B.jpg (28524 bytes)  wpe1D.jpg (43521 bytes)
Latrodectus hasselti, body length female 7mm
Body and legs are shiny black, with a distinct red stripe on the back and the red time-bottle mark (small photo) on the bottom of their abdomen. Red Back spiders build a tangled web on the wall, rubbish and old furniture in the garden. They like afternoon sunshine so they are found mostly on the western side of the garden. They have a very bad name in Australia because their bite is known to be fatal. Since the invention of the anti-venom twenty years ago, no one has been killed. However, they bring a lot of business to the pest control company. Most of my friends will call pest control company immediately once they find the Red Back in their garden. To read more information on Red Back Spiders, the symptoms of Red Back Spider bite and how to control Red Back Spiders, please click on here.
