Triangular Spider - Arkys lancearius
This page contains pictures and information about Triangular Spiders that
we found in the Brisbane area, Queensland, Australia.
- Female, leg to leg 15mm
- This is a beautiful spider. We can easily find them in bushland in
Brisbane, although we never saw them in our backyard. Its abdomen is triangular to
heart-shaped , with white spots on its bright orange body. Its two pairs of
front legs are with strong spines for capturing prey. Its two hind pairs legs
are relatively small.
- Although they
are in this ARANEIDAE
family, which is famous in web building, they do not build webs.
They only use their silk for safety lines and egg sacs.
- Triangular Spiders have very small eyes and expected to have poor eye
sight. They do not jump like Jumping
Spiders. Instead they employ the sit and wait hunting method.
- Sometimes the spider hangs itself in mid air with a few silk wires and
waiting for prey.
- Usually female has a larger abdomen.
- Triangular Spiders are sometimes
found on or under green leaves, waiting for prey.
