Spider Photos - Red Back

Here's some photos of Redback spiders as well as links to other members of the Lactrodectus family - brown widows and black widows! Spiders of the genus Steatoda belong to the spider family Theridiidae, or the cobweb weavers. Also known as Combfooted Spiders, this family includes a number of well known arachnids, including the American house spider, Achaearanea tepidariorum, and the redback and widow spiders, Latrodectus spp.. Steatoda spiders are found throughout the world, in both temperate and tropical climates. They are small to moderately small (3-9 mm) spiders with oval abdomens; they may be reddish, brownish or black, with most species exhibiting a white band at the front of the dorsal abdomen which may resemble a collar. Brown widows are easily confused with the harmless cobweb spiders so not all ID's below may be correct!! For more information on these spiders, click here.

The Red-back is found in all parts of Australia except in the hottest deserts and on the coldest mountains. It is the only dangerous spider with an Australia-wide distribution. Red-backs are very common in Summer. The female Red-back has a spherical satin-black abdomen with an orange-red stripe. The abdomen is usually about 1 cm in diameter. Eight long delicate legs arise from the tiny front segment of the body. The male is only about one-third the size of the female and is considered harmless to humans because his fangs are so small. The male's markings are not as bright as the female. It is usually easy to identify a female Red-back although her stripe may be orange, pink or even light grey.

Hello Glen. I took a few pics and include them here. Feel free to use them on your site if you wish. I would be interested in your opinion in the matter. Regards Alex

Hi... I was thinking this was a redback spider with some colour variation...but after searching the net it looks more like a brown widow except that it does have the red. (the red is also on the ventral side and on the front of the abdomen.) The colour here has not been altered... What do you think? Young female redback? I found her in my house, northern suburbs of Perth. thanks, kelle

Hi Glen, I was going through all my pics the other night and came across some other spider photos that had taken. Free to use on your site. Cheers BJ

What is this?

Hi Glen,
 Some photos attached - am pretty sure this is the dreaded redback! Found in garage in suburban Melbourne.  Cheers,  Raj

Hi again Glen, I've found another interesting spider in my house. This time one that looks  suspiciously like a Redback, though I'm not entirely sure because of the size  of the abdomen. In any case, I'm eager to see what you think. As with the huntsman last time, feel free to use this image on your website. Thanks very much for your time and help!


Reply: Certainly looks like a redback to me!!

Hi There, I came across this little fellow inside an overturned kids sand pit in our back yard today and thought that it may be a relative of the red back family. Anyhow my kids would like to find out for sure and I would just like to know if you have ever come across one marked like this or if it is actually a red back.

Location: Kurri Kurri N.S.W

Thanks, Adrian, Bianca & Gabrielle

Today's photos are of a red back that has made its home in our pool fence. Some large green caterpillars were busily munching on the leafy green shoots of one of my pot plants, so I took them off and put them in the garden bag next to the fence. Worst move that caterpillar ever made was to escape from the bag, straight into the red back's messy web. You can see by the size of the caterpillar compared to the red back, what a feat it was for the spider to wrap it and lift it off the ground several centimetres. These shots were taken with a Panasonic Digital Video camera in still mode. Click on the photo for a larger view.

The red back is under the caterpillar in this shot. You can just see its legs.

Here she is on the tail end of the caterpillar on her way around the body.

The small dots are red back babies. Here the red stripe is clearly visible.

The red back disappears up the open end of the post in the pool fence. Must have been camera shy!!
