The redback spider is a highly venomous spider. It is thought to come from Australia, but it now also lives in Southeast Asia, Japan and New Zealand. It often lives close to people, in warm, sheltered places in and around homes, so it matters a great deal for safety.1

It lives in warm, sheltered places, commonly near or inside human homes and other buildings. Food scraps and lights attract the insects it hunts, which brings the redback closer to people.1

It mainly catches insects, but also spiders, small lizards and occasionally even snakes or a mouse that become caught in its web. It squirts sticky silk over the prey, bites it repeatedly, wraps it in silk, then sucks out its liquefied insides back at its retreat.1

Sida loo aqoonsado

The adult female has a round, shiny black body with a red stripe on the top of the abdomen.1
Underneath, she has an hourglass-shaped red or orange streak.1
The female's body is about 1 cm long, with slender legs.1
The male is much smaller, 3 to 4 mm long, light brown with white markings on the upper abdomen and a pale hourglass marking underneath.1
Its web is an irregular, untidy tangle of strong silk, usually in a warm, sheltered spot.1

Inta badan lagu khaldaa: The false redback spider (Steatoda capensis) has a similar build but is uniformly black or plum-coloured, and it has no red stripe on its abdomen.1

Qaniin

Maxay samaysaa suntiisa (qaniin ama mudid)?

The venom is neurotoxic to vertebrates, meaning it attacks the nerves, and it causes a condition called latrodectism. Pain starts around the bite and typically becomes severe, spreading up the bitten limb and lasting for over 24 hours. Localised sweating in patches of skin is highly indicative of latrodectism, and nausea, vomiting, headache and agitation may indicate severe envenomation.1

Intee buu dadka khatar ugu yahay?

Khatarta dadka: HalisQaniinyo waxay u baahan tahay dhakhtar. Dhimashadu aad bay u yar tahay.

The redback is one of the few spider species that can seriously harm humans. Because it often lives in buildings, it is responsible for a large number of serious spider bites in Australia.1

Muxuu sameeyaa marka uu baqo?

Its bright scarlet markings may serve as a warning to potential predators.1

Badbaado

Weligaa ha taaban, ha qaban, hana ku ciyaarin xayawaan duurjoog ah, xitaa mid yar, xitaa haddii uu u muuqdo inuu hurdo ama dhintay.
Meel u bannee. Haddii aad mid la kulanto, deg, tartiib dib ugu noqo oo u daa inuu jidkiisa maro.
Haddii mid ku qaniino: deg, ha dhaqaaqin, wac lambarka gurmadka degdegga ah (112, 000, 911) ama si degdeg ah u tag isbitaalka. Xusuuso sida uu u egyahay, sawir ayaa caawiya.

Xaqiiqooyin

A male redback can successfully mate with a female katipō, a related New Zealand spider, producing hybrid offspring.1

Males often mate with a female who may then eat them, a behaviour called sexual cannibalism that many arachnids show while mating.1

In laboratory tests, redbacks survived an average of 100 days, and sometimes over 300 days, without food.1

After mating, a female can store sperm for up to two years and use it to fertilise several clutches of eggs.1

Spiderlings and larger females steal food from other spiders' webs, and spiderlings sometimes eat their less active siblings.1
