Triangular Spider - Arkys lancearius
FAMILY ARANEIDAE
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.
Female
- Usually female has a larger abdomen.
Male
- Triangular Spiders are sometimes found on or under green leaves, waiting for prey.
