Missulena occatoria

Species of spider

Missulena occatoria, known as the red-headed mouse spider, is a species of spider found in Australia, from open forest to desert shrubland. It is the most widely distributed Missulena species, occurring throughout mainland Australia. This is possible because the spiderlings disperse via wind (ballooning). Normally this only occurs with araneomorph spiders, mygalomorph spiders normally disperse by walking. Missulena venom may be very toxic, but few cases of serious envenomation have been recorded. Most recorded bites only caused minor effects, with Australian funnel-web spider antivenom having proved effective as a treatment.
