White tail spiders (Lampona cylindrata and L. murina)

A type of spider commonly found in Australia and New Zealand. These spiders are often feared due to their reputation for causing necrotic (dead) skin lesions, but the extent of their danger is a topic of debate among experts.

Description:

White tail spiders are small and have distinctive white markings on the end of their abdomen. They are usually brown or grey in color and have a cylindrical body shape. These spiders are often confused with other species of spiders, such as black house spiders or wolf spiders.

Habitat:

White tail spiders can be found throughout much of Australia and New Zealand. They prefer dark, cool places such as crevices, cracks, and corners of houses, sheds, and other structures. These spiders are also commonly found outdoors in garden debris, under rocks, and in tree bark.

Behavior:

White tail spiders are nocturnal and will often hunt for prey at night. They are known to feed on a variety of insects and other spiders. These spiders are also known to be cannibalistic, with females often preying on males after mating.

Potential Danger:

White tail spider bites can cause a range of symptoms, including mild to moderate pain, redness, swelling, and itchiness. In some cases, a necrotic lesion may develop at the site of the bite. However, there is still debate among experts as to whether white tail spiders are actually responsible for necrotic lesions, as other factors such as bacterial infections may also contribute to the development of these skin conditions.

It’s important to note that white tail spider bites are generally not considered dangerous or life-threatening to humans. Most bites will heal on their own within a few days to a week. However, if you experience severe symptoms such as difficulty breathing or swelling in your throat, seek immediate medical attention.

Conclusion:

White tail spiders are a commonly feared spider species due to their potential to cause necrotic skin lesions. While the extent of their danger is still a topic of debate, it’s important to take precautions to prevent spider bites, such as wearing protective clothing and keeping living areas clean and clutter-free. If you do encounter a white tail spider, try to avoid provoking it and seek medical attention if you experience any concerning symptoms after a bite.
