Latrodectus hasseltiCommon name: Red-back Spider
Distribution: This spider has been found throughout Australia.
Remarks: The females of the Red-back Spider can grow to have a body length of approximately 14 millimetres, but the males only reach about 3 millimetres.
Female Red-back Spiders can be dangerous to humans, however the fangs of the males are too small to penetrate the skin. But the spiders are not aggressive and bites usually occur when the spider is accidentally handled. If bitten, medical attention should be sought as soon as posssible as there is an antivenom for the bite.
This spider has been seen in January and March.
