Heavy jumper spider
Hyllus diardi
Family Salticidae
updated Nov 2019
Where seen? This furry white spider is sometimes seen among mangrove vegetation. It is rather large for jumping spider and is quite active during daylight.

Features: Body to about 1cm long. Body furry white with dark markings. Like other jumping spiders (Family Salticidae) it has huge eyes. On the 'face' is a pair of enormous eyes with smaller eyes around the head. These are not compound eyes like that of insects. Nevertheless, these eyes allow the spider to judge distance accurately.

What does it eat? Like other jumping spiders, it does not build a web. Instead, it hunts on the move, attaching a silken line to a support before 'bungee jumping' onto suitable prey.

Jumping babies: Male jumping spiders perform amusing rituals to entice a female to mate with them.
