This is a close-up showing eyes of the Net-casting spider. It has an "alien" look when you get this close. This is the image on my HOME page, and is the same species as shown in the two photos above. A long extension tube on standard lens was used for this shot. The extension tube was made from plastic plumbing pipe - my standard extension tubes are not long enough for this high magnification.

The Net-casting spider sets its trap at night. The rectangular white net is spread between first two pairs of legs. The third pair of legs has threads to stabilise the "net". The fourth pair of legs are used to hang onto its support. When a passing insect comes near the net it splats it over the victim, and tangles it in the trap.
