Redback spider

Red-Back-5
Redback spiders are not aggressive, and rarely leave the web. However caution is advised as their bite is very poisonous and potentially fatal for children or the elderly.
After a bite, the onset of pain may be delayed for five minutes then increase in intensity. Subsequent symptoms vary but have included:
• nausea
• vomiting
• abdominal or generalised pain
• sweating
• restlessness
• palpitations
• weakness
• muscle spasm
• fever.
Anyone bitten by a redback spider should seek medical attention.

Redback spider

red-back-4
Redback spiders, Latrodectus hasselti,
Mature female redbacks are jet black spiders with a variable red stripe on the back of their spherical abdomen. Immature females are smaller, usually brown with whitish markings.
Their tough, untidy webs are usually near the ground with the spider hiding in a shelter tucked in a corner, often guarding her round woolly egg sacs.
Male redback spiders are rarely seen. They are small and brown with red and white markings.

Redback spiders are found throughout Australia, in drier habitats and built-up areas. They are common in dry places around buildings, outdoor furniture, machinery and stacked materials.
In the bush, redback spiders nest under logs and rocks. There is some evidence to suggest that redbacks are not native to Australia.
Redback spider bites usually occur when part of the body comes in direct contact with the spider or its web.
