Redback spiders are found throughout Australia and can be very robust hunters living in leaf litter or burrows. If you’ve been finding redback spiders around your home, then it may be time to contact a professional pest controller. I find those all the time in Alabama and they are paralyzed for the wasp larvae to eat while they grow. Feeding Habits: arthropod-feeder, carnivorous, insectivorous, predator How to get rid of Redback Spiders. One other thing, if the spider was pulled out of the mud nest, it was already doomed. In fact, almost every sac I had produced a percentage that had the spots or stripes so I don't think it's as uncommon as might be believed. I found that red spots were common on the back and sometimes they blended together to make a stripe. I even tried breeding for a particular pattern that was pretty cool but I only got 4 offspring from the female that had it before she died of old age and those produced many aberrant patterns but none like the original. I've had many mactans retain so.e or all their juvenile coloration into adulthood. I've raised widows for years, mactans mostly, and that is a typical juvenile. mactans juices and males look like that and I'd bet that's what it is. A guide to Funnel-web spider identification, The Medical Journal of Australia, December 8/22 Distribution of the Funnel Web Spiders, in Covacevich, Davie & Pearn (eds), Toxic Plants and Animals: a guide for Australia: 313-21 CRC Handbook of Clinical Toxicology of Animal Venoms and Poisons CRC Press Inc, Boca Raton, Florida, USA Funnel Webs: separating fact from fiction, ANH 24(3): 32-39 Animal Family: Theridiidae Where Found: Australia, also New Zealand and Southeast Asia Body Length: female 10 to 13 mm (0.4 0.5 in.), male 4mm (.16 in.) Conservation Status: Not Evaluated Other interesting Redback Spider facts: Only female redback spiders are dangerous to humans. The female likes to live in warm sheltered places and makes a web to. The adult female spider is usually black and usually has a red stripe on its back. The female's body is about 1 centimetre long and the male's body is about 3 millimetres long. The redback spider ( Latrodectus hasselti ), also known as the Australian black widow, 2 3 4 is a species of highly venomous spider believed to originate in South Australia or adjacent Western Australian deserts, but now found throughout Australia, Southeast Asia and New Zealand, with colonies elsewhere outside Australia. However, there have been no fatalities since the introduction of antivenom. The redback spider is a venomous spider that lives in Australia. The venom has a neurotoxin component that attacks the human nervous system and, in the worst cases, can result in death. Danger to humansįunnel-web bites are dangerous and first aid should be given immediately using the pressure bandage/immobilisation technique (as for snake bite) and the victim taken to hospital and given antivenom if necessary. Males leave their burrows and wander over summer and autumn to find females and mate. This can be any suitable hideaway that is dark, moist and cool, like a cavity under a rock, or even in a shoe left outdoors.Ī number of other spiders are often mistaken as funnel-webs, including mouse spiders, trapdoor spiders and even Black House Spiders. This is why males that have spent the night in search of a female have to seek cover at dawn. ![]() Nor do they jump onto, or chase people, or live in houses - these are all urban myths.ĭry daytime surface conditions will dehydrate funnel-web spiders and also expose them to birds and lizards. ![]() The venom of juvenile and female Sydney Funnel-web Spiders is much less toxic. However, it is not true that all funnel-web bites are life-threatening. Again, it is true that Sydney Funnel-webs have one of the most toxic venoms (to humans) of any spider. They also sometimes enter and become trapped in houses. Male Sydney Funnel-web spiders have a habit of wandering into backyards and falling into suburban swimming pools, where they can survive many hours.
