Poltys laciniosus (Helen Smith)|
(or perhaps Poltys noblei)
female: 9 mm|
male: 2 mm
This spider may build a small web at night but during the daylight hours it normally rests on dead twigs where its upright posture and good camouflage colours make it very difficult to see unless it moves
Uncertain but this non-aggressive spider probably is totally harmless to humans
The most obvious physical characteristic of this species is the way it adopts an upright posture with the long, finger-like top of its abdomen pointing vertically. Its camouflage colours make it very difficult to see when it is resting on a bark surface. On the other hand, it has distinctive yellow-orange bands on the insides of its legs which can only be seen when the legs are extended. Please note that some other Poltys species are very similar in appearance so identification to species is probably impossible for anyone who is not an expert arachnologist.
This species makes a fawn/grey egg sac which is attached to a dead twig.
Known Range: Recorded as being in coastal parts of Australian States but not Tasmania.
Spider(s) with a very similar appearance: Poltys illepidus.
