Spider

The majority of Australian spiders are new to science. Most of the spider species in the rest of the world have already been described.

Australia leads the world in the number of venomous spiders as well as the toxicity. However, of almost 10 000 species of spiders in 70 families throughout the country, most are harmless to humans and interesting to study.

Redback Spider

All spiders in Australia are venomous but only two have caused deaths, the Funnel Web and Redback.

The Redback is the most well known Australian spider and found in all areas except in the hottest deserts and high in the mountains.

She can store sperm up to two years then lay 10 egg sacs, each containing about 250 eggs, and can repeat this a week later.

Latrodectus hasselti

Closely related to the Black Widow and identical except for the red dorsal stripe.

The Redback "venom is highly neurotoxic, which is to say that it attacks the central nervous system causing intense pain, profuse sweating, difficulty in breathing, loss of consciousness, violent convulsions and, finally...Death."

Prior to the introduction of specific antivenom in 1956, Redbacks had been responsible for thirteen deaths in Australia. None since!

Spider web

All spiders are predators with eight legs, eight eyes, fangs and venom but the the most prominent feature is the ability to produce silk.

Silk is used as a safety-line, to catch prey, wrap up prey and to make egg sacs.

It is also used for transport, shelter and courtship.

Golden Orb Spider

The Golden Orb spider gets her name from the beautiful golden, orb-shaped web that she makes. This web is the largest and strongest in the world.

The tiny males live on the edge of her web feeding on small insects. They are so small that they can sneak in for a quickie without the female noticing. But if they are caught they may get eaten. surprise

Huntsman Spider

Huntsman spiders are those big, hairy, scary, long-legged spiders we often find behind curtains, in the shower cubicle and under the car's sun visor.

These timid creatures are harmless and will run from humans at lightning fast speeds.

The design of the legs allows the Huntsman to run sideways as well as forward.

Daddy Long Legs

Daddy Long-legs hunt, kill and eat Redback Spiders, House Spiders, Wolf Spiders and more. An ideal pet to keep in the house.

When hunting other spiders it will tap the victims web to attract it, quickly envelope it with silk and then inflict the fatal bite.

When threatened by a touch to the web the Daddy Long-legs become invisible by vibrating rapidly and becoming blurred. Their main predator is the vacuum cleaner.

Black House Spider - Badumna insignis

Black House Spiders (or Window Spiders) are timid and rarely bite.

Named for its habit of building untidy looking webs at the corners of windows and doors.

Venom toxicity - the bite of the Black House Spider is poisonous but not deadly. Symptoms include pain around the bite site, sweating, headaches and giddiness.

Flower Spider - Thomisus spectabilis

Flower Spiders (or Crab Spiders) are colourful and camouflage well in flower petals. This serves a dual purpose of hiding from potential predators and concealing from possible prey.

They feed on nectar feeding insects including bees.

Huntsman I think most aussies have a scary Huntsman story.
Spider Wasp

This spider has been immobilized by the sting of a wasp and will become living food for the larvae.

Garden Orb Spider

Garden Orb Weaving Spiders are common in gardens during summer. They build their webs in the evening and before daylight will sometimes eat the web, then hide all day.

They are non-aggressive and low risk to humans but walking into a web at night can cause panic, especially if the spider is on your face.

Harry the Spider

All the indoor pics were taken inside my house. I removed the Redback, the Daddy Long Leg ate the Black House spider and Harry the Huntsman is still here. smile

Christmas Spider - Austracantha minax

Jewel Spiders (Christmas or Spiny spider) are orb weavers.

These tiny spiders are usually found on a web strung between two bushes.

They look like a creature you don't wanna touch.

Banded Garden Spider - Argiope trifasciata

Banded Garden Spider or Banded Argiope

Generally seen arse-up in the centre of an orb web, with legs together in pairs. Trifasciatas are found throughout Australia around Autumn. Often mistaken for the St Andrews Cross spider which is only found in the east.

These awesome creatures are totally harmless.

Argiope trifasciata

Sand Spider

Tiny sand spiders hiding in the dunes at Cape Range NP, Exmouth.

Wait until dark, grab a torch, enter the sand dunes and hold the torch about eye-level. The bright pinpricks of light in the sand are reflections from the spiders eyes. I saw up to 10 from one location.

When alarmed the spider will quickly disappear into the sand.
