Australomimetus spinosus (QM)|
(also matching photos on Robert Whyte's Arachne website)
female: 5 mm|
male: 4.5 mm
Usually on green leaves or under fallen logs but are sometimes found in the webs of other spiders they are attacking; they probably do not make
substantial webs of their own
this species is relatively small, timid and secretive; bitings are rare
Australomimetus spinosus seems to be the most common member of this genus to be found in Eastern Australia but there are many other Australomimetus
species in this country and most are too similar in overall appearance for easy identification.
These spiders are called pirate spiders because they feed on other spiders rather than on insects. One of the photos included on this page shows an
immature male specimen feeding on a female Parasteatoda tepidariorum. Australomimetus species do not use webbing to catch their prey but may use a small
amount as protection for their eggs and subsequent spiderlings.
Mimetids are characterised by a row of large curved spines separated by sets of small spines on the tibia
and the next segment (the metatarsus) of the first pair of legs. The first two pairs of legs are much longer than the other two pairs and sometimes fold
back over the spider's body. All legs are obviously spiny but the spines are not as erect as on oxyopid spiders.
