Australian Heteropoda species are difficult to distinguish from each other without the aid of a stereo microscope as well as some information regarding the
locality in which a particular specimen was found. The markings on their upper surfaces vary slightly from specimen to specimen but not greatly from species to
species. For this reason each species can only be identified with confidence by examining its genital structures under the microscope.
Many people have based their identification of a Heteropoda specimen on the photo labelled as Heteropoda cervina by (Mascord) in his 1970 spider booklet.
It is likely that Mascord correctly named this spider but in her 1994 paper (Valerie Davies) of the Queensland Museum reported that there
are at least 37 Australian Heteropoda species and that several of them, including H. cervina, can be found in North Queensland, which was where the specimen in Mascord's photograph was found.
Heteropoda jugulans is probably the most common species found in South Queensland, although its range appears to extend as far north as Cape Tribulation. There are also at
least nine other Heteropoda species recorded for parts of South Queensland, most of them with a more restricted range than that of H. jugulans.
Being nocturnal hunters, Heteropoda species often wander into houses in the evenings and may be found on walls and ceilings as well as in sheds and letter boxes around the house.
They are readily caught in pit traps made by burying 10 litre cylinders into the ground in a bush setting because they are primarily woodland spiders that hide in crevices under loose bark.
Spider(s) with a very similar appearance: Most other Australian Heteropoda species and some other sparassids.
