Habits
Spiders are found in all terrestrial habitats across Australia and some have even adapted to a semi-aquatic lifestyle.
Spiders
can commonly be found in leaf litter and under rocks, logs or the bard
of trees. Many dig burrows in the soil, while others spin distinct webs
amongst vegetation. |

Funnelweb Spider
This
spider is found in all states across Australia. The female lives in a
long web funnel which she constructs in loose soil or debris in fairly
moist and sheltered places. The mature male is more of a wanderer,
especially during January to April, and for this reason may enter houses
particularly when his habitat is disturbed
Both
sexes are black to red brown and their cephalothorax is shiny. Body
length of a female is 30mm and of the male 25mm. The male has a large
spur on the inner margin of each of the second front pair of legs.
The
venom of the Funnelweb Spider is extremely toxic to humans, that of the
male spider being much more so than that of the female. |

Redback Spider
The
Redback Spider is found all over Australia in open bushland, but is
especially common in urban areas. As one of a number of spiders that
prefer inhabited areas, and it often builds its web in places like sheds
or outhouses, bins, drains, beneath kids toys and outdoor furniture.
Their webs are easily spotted, they are very messy and sticky and
collect leaves and other rubbish blown into them by the wind.
Their
webs are usually below waist height and when cleaned should first be
treated otherwise a venomous bite may be incurred .However, be aware of
Redback spiders inhabiting roof voids, as they sometimes get transferred
up there with roof trusses or air conditioning ducts.
Bites
are always from females as the male is much smaller and has jaws that
are unable to penetrate the skin. The venom is highly toxic to humans
but effective anti-venom is widely available.
Redback
spiders are shiny black in colour and have a distinctive red mark on
its abdomen. The female length is 10-14mm and the male 2-3mm.

White Tailed Spider
The
White Tailed Spider is a dark grey, cylindrical spider. The legs have a
dull reddish tinge, which are banded in a dark grey/brown colour. They
have a distinctive white tip on their abdomen. The females
are up to 18mm long and the males 12mm.
White
Tailed Spiders are vagrant hunters that live beneath bark, rocks and in
leaf litter and logs, in bushland and gardens and they are often seen
in houses. They are rumoured to be attracted to linen, sometimes
brought in when bringing in the washing.
They are most active at night when they wander about hunting for other spiders, their preferred food.
During
summer and autumn White Tailed Spiders are often seen in and around
houses where they find both sheltered nooks and crannies and plenty of
their favoured black house spiders and daddy long legs.
If
bitten try to catch the spider for later identification. If pain or
inflammatory symptoms develop, seek medical attention. Apply a cold
pack if pain persists. |

Sydney Brown Trapdoor Spider
This
spider is often confused with the Funnelweb. It is brown to dark
brown, is also more hairy and its holes are found in more open and drier
areas. The length of the body of the female is 25-30mm and the male
20mm. The male has boxing glove palps. Their bites are usually only
painful but not toxic.

The Mouse Spider
The
female is often mistaken as a Funnelweb because of its shiny
cephalothorax. Unlike the Funnelweb, the female mouse spider has very
short legs, moves slowly, is not aggressive and lives in open day areas
where its holes are often easily seen.
The
body of the female is 25mm long and the male 10-20mm. There are no
spurs on the legs on either male or female. Its bite is painful but not
toxic. |

Huntsman Spider
These
are large fierce looking spiders, sometimes being 100-120mm wide,
including body and legs. They are brown in colour and live under bark
of trees and in roof voids of houses. They are also found in cars,
which were parked beneath large trees. They are not aggressive and if
provoked to bite no symptoms of toxicity follow. |
