Spider hoax clogs inboxes Australia-wide
This month the Queensland Museum Inbox has been flooded with inquiries concerning a supposedly very dangerous spider, whose bite is believed to cause severe necrosis of the flesh. The email claims it is a new Huntsman-like spider recently arrived to Eastern Australia, is heading for Western Australia, and is breeding at an alarming rate. So, is this story true?
No. While the image is of a real spider, the Brown Recluse Spider (Loxosceles reclusa), the story is false. A few points from our Senior Curator of Arachnology:
- this series of photos have been around for years, originating in the US and having nothing to do with Australia
- the spider does not cause the wound
- our native White-tailed Spiders (Lampona spp.) have also been erroneously blamed for the development of a similar lesion
- no Australian spider is know to have necrotic (tissue-destroying) venom
- the causes of these wounds are diverse and not related to spiders
- although the spider does occur in Australia, it only lives in a very restricted suburban area in a southern Australian State, has been here for approximately 20 years, has not extended its range, and no bites have been recorded from it
