Rufous Net-casting Spider (♂)

Asianopus subrufa

Description:

This crazy guy was found exploring the walls inside our home. No Deinopis food there. About 22mm long body and 80mm across including legs. The very large male palps can be seen like black wheels.

Habitat:

Outer urban home.

Notes:

"The two biggest eyes are specialised for providing outstanding low-light night vision. They have enormous, compound lenses that give a wide field of view and gather available light very efficiently. The lenses have an F number of 0.58 which means they can concentrate available light more efficiently than a cat (F 0.9) or an owl (F 1.1). Each night a large area of light sensitive membrane is manufactured within these eyes (and rapidly destroyed again at dawn). ..... White faecal spots on a leaf below the net are aiming points placed there by the spider. " - Australia Museum
