Redback Spider

Redback Spider

The redback spider, also known as the Australian black widow, is a species of highly venomous spider thought to have originated in South Australia or adjacent Western Australian deserts, but is now found throughout Australia, Southeast Asia, and New Zealand, as well as in colonies elsewhere outside Australia.

Redback spider, belongs to the worldwide genus Latrodectus, which includes widow spiders.

The adult female can be identified by her spherical black body with a noticeable red stripe on her upper belly and an hourglass-shaped red/orange streak on her underside.

The redback spider (Latrodectus hasselti) is one of the deadliest spiders in Australia. It’s actually more dangerous than the black widow spider because its bite contains an extremely potent neurotoxin called latrotoxin. This toxin affects the nervous system, causing symptoms such as muscle weakness, paralysis, and even death.


Black Widow Spider

Black Widow Spider

The black widow spider (Latrodectis mactans) is also known as the “widow” spider. Its venom is less toxic than the redback spider’s, but still very deadly. Like the redback spider, the black widow spider lives in Australia. Both species are found throughout the country, although the black widow spider prefers drier areas.

The venom of these little spiders contains the neurotoxic latrotoxin, which causes the condition latrodectism, both of which are called after the species.

Female widow spiders have disproportionately large venom glands, and their bites are especially dangerous to large vertebrates, including humans. Only the females’ bites pose a threat to humans. Latrodectus bites rarely cause death or major complications, despite their notoriety.


Brown Recluse Spider

The brown recluse spider (Loxosceles reclusa) is one of the deadliest spiders in the world. It has been responsible for more deaths than any other spider species. This spider is native to North America, but has recently expanded its range into Europe and Asia.

Brown recluse spiders are found throughout the United States, Canada Australia. They are also found in parts of South Africa, Argentina, Chile, and Mexico. These spiders are typically found in wooded areas, such as forests, parks, and gardens.

Arachnids native to Australia, sometimes known as funnel-web spiders. Until recently, it was considered to be a part of the Hexathelidae family; however, recent research has shown that it should be considered its own family.

Each and every member of the family was born and raised in Australia. Atrax, Hadronyche, and Illawarra are the three genera that make up the Atracidae family, which has a total of 35 species.

The bites of spiders belonging to six of the family’s species have been known to cause victims severe injury. Certain members of the family are known to produce venom that is harmful to humans.

Both the Sydney funnel-web spider (Atrax robustus) and the northern tree-dwelling funnel-web spider (Hadronyche formidabilis) are capable of inflicting fatal bites; however, since the development of modern first-aid procedures and antivenom, there have been no fatalities associated with these spiders’ bites.


White-tailed Spiders

White-tailed Spiders

White-tailed spiders are spiders that are indigenous to southern and eastern Australia.

They got their name from the whitish tips that are located at the end of their abdomens, hence the name. The body length can reach up to 18 mm, and the limb span can reach up to 28 mm.

Common species are Lampona cylindrata and Lampona murina. Both of these species were brought to New Zealand by humans at some point.

It is possible for the bite of a white-tail spider to cause nausea and burning pain, which may be followed by swelling and itching in the area where the bite occurred.
