There are thousands of different types of spiders in Queensland and while they all are different from each other depending on their environment, food source and other factors, they all have some characteristics in common. All spiders have 8 legs, a two-part body and biting fangs which vary in length depending on the type and gender of spider. Most spiders have 8 eyes but despite this, they can’t see well but feel and smell through special hairs on their feet.
There are two distinct groups of spiders – primitive spiders and modern spiders. Primitive spiders as the name suggests are the least evolved and have remained unchanged for millions of years. In Queensland they include the trapdoor and funnel web spiders. The common spiders we encounter in our daily lives are the moderns. Of the dozens of different types inhabiting south-east Queensland, the most frequently seen include the wolf spider, red back spider, white-tailed spider, huntsman, black house spider and daddy-long-legs.
Black House Spider – black or very dark, hairy indistinct pattern on body and legs.
Daddy-long-legs – introduced from Europe, now widespread – dark colour, small, pea-sized body, very long, fine legs.
Huntsman Spider – brown variety has black X on head, black chevrons on body, black V under abdomen; grey variety is very large with leg span of 230mm, brown stripe down centre of abdomen.
Red Back Spider – Females are black with are strip down the back; males black with white strip – no red. Legs are thin, pin-like in both male and female – adults can span 50c coin.

Wolf Spider – Large eyes on top and front of head which is patterned, black, bell-shaped mark on body, completely black underneath – leg span up to 7cm.
Female spiders lay their eggs in an egg sac which can contain hundreds of eggs, depending on the type of spider. Usually the eggs take only a couple of weeks to hatch. The spiderlings either walk from the egg sac or throw out a web which is carried on the wind to a new location. Spiderlings moult up to 5 times, again depending on the type of spider. Most spiders, once they reach adulthood, no longer moult.
Black House Spider – webs are found under guttering, on brick walls and in the corners of doors, windows and eaves.
Daddy-long-legs – fine webs are messy and disordered – found inside houses in corners and behind furniture.
Huntsman Spider –natural habitat is under bark on trees but adapts too indoors where it runs across the walls while hunting at night. The grey huntsman likes open forest but indoors prefers flat places like behind paintings.
Red Back Spider – like warm, sunny spots on northern and westerns parts of buildings, around barbeques, under outdoor tables and chairs, in pipes and are often found in garages.
White-tailed Spider – natural habitat is in leaf litter and under bark.
