Arkys lancearius, the triangular spider,[2] is a common Australian spider belonging to the family Arkyidae.[1] It is an ambush hunter, commonly found resting on leaves and ferns or hanging from just a few threads of silk. The front two pairs of legs are large, suited for grabbing small insects, while the rear pairs of legs are much smaller.[3]
Description and habit
The body length of males is about 5.5 millimetres (0.22 in), while that of females are around 8 millimetres (0.31 in). Body colour varies from yellow or orange to red with pale jewel-like markings on the heart shaped abdomen. Egg sacs are produced in January or February and are a deep pinkish cream colour. They are usually around 8 mm in diameter and are covered in lighter coloured threads. Each sac contains about 70 eggs, each 0.7 mm in diameter.[4]
