Scytodes thoracica (RM)|
(Note: The images included on this page may be of more than one Scytodes species)
female: 6 mm|
male: 4 mm
In caves and in the corners of open, man-made structures such as sheds and bridges as well as internal window ledges
Minimal hazard because the fangs and chelicerae cannot open wide
This spider normally stands high on stilt-like legs. The carapace is unusual in sloping upwards towards its rear
end, whereas the abdomen slopes downwards. Scytodes does not construct a typical egg coccoon but holds a batch of
eggs loosely tied together with silk under its chelicerae.
Scytodes is also known as the spitting spider because instead of using venom to immobilize its prey it 'spits' mucilaginous material over the prey thus
preventing them from escaping. It also does not build a web for catching insects but may sometimes be found in a dense woolly natted web constructed within a convenient crevice.
Scytodes thoracica is cosmopolitan because it is easily carried abroad in crevices on man-made objects. It is not clear if any of the species known to be found
in Australia are endemic to this country.
Spider(s) with a very similar appearance: Scytodes fusca.
