Two-spined spider

Poecilopachys australasiae


The females are brightly coloured about 7-8 mm in length with two white horn like spines. The male is smaller and do not possess the distinctive spines of the female


During the day it sits quitely on the underside of a leaf. It emerges at night and construct a small (rather tatty looking) orbweb. It uses a crude form of pheronome to attract leaf roller moths which end up in the web and get eaten. In the morning, the spider dismantles the web and eats the silk so it can be recycled for the next building effort.


The two-spined spider is a native of Australia and discovered in New Zealand in the early 1970's. It is believed they may have arrived in New Zealand by "ballooning" across the Tasman. The ability to "Balloon" is a common feat of many spiders
