Slater-eating Spider
Dysdera crocata
Family: Dysderidae ID: Koch, 1839
Habitat and Biology
As its name suggests, the slater-eating spider prefers a
diet of slaters (or wood-lice) which it captures with specially elongated fangs.
It is believed to have been introduced into Australia from Europe and only occurs
in the south-eastern part of the continent. It prefers damp habitats under logs,
rocks, rubbish etc., places it is most likely to encounter prey. It is relatively
common in urban gardens. Apparently this spider has a strong aversion to ants,
which limits its distribution in this country. The slater-eating spider builds
a silken sac-like retreat in which it rests, moults and lays eggs. The eggs
are wrapped in silk and guarded by the female until hatching.
