I have not been able to photograph a huntsman spider yet, but a friend in St. Katherine has and generously shared her pictures so I could write a post about this beauty!
This is a spider in the huntsman family of spiders (Sparassidae), specifically Eusparassus walckenaeri. There are 33 spiders in the Eusparassus genus, and they can be found in Africa, Asia, Europe, and Peru. Huntsman spiders are known for their incredible speed. In fact, it’s because of their lightning speed that the Jebeleya Bedouin call them beraira.
These huntsman spiders are large with flat bodies that are dark brown to orange-brown in color, with a pattern of spots and chevrons. The bodies can be from 1 to 2.5 cm in length, with the females being larger. The legs have dark bands of color and, although the legs of most spiders are perpendicular to their bodies, the legs of huntsman spiders are not. Their legs are angled and twisted in such a way that they move with a sideways crab-like motion. (Huntsman spiders are sometimes called giant crab spiders.)
Huntsman spiders are nocturnal hunters and feed on small and large insects, especially cockroaches, so a spider would be a welcome find in your home! And there’s no reason to be afraid of them; their venom won’t hurt you.
While these spiders may be imposing hunters, they are, of course, prey to other animals, especially to a family of wasps known as “spider wasps” (Pompilidae). A female spider wasp uses its venomous sting to paralyze a spider and then drags the spider to her nest or burrow. There, she lays an egg on the spider, which is anesthetized but alive. The wasp larva hatches and proceeds to feed on the spider, saving the vital organs for last, until it finally spins a cocoon and eventually emerges as an adult wasp.
These huntsman spiders can be found in open ground, but I have never spotted one in the wadis. They can also be found indoors and I’m pretty sure I have seen (some species of) huntsman spiders scuttle through the communal seating area of a camp in Ras Sidr. Have you spotted these huntsman spiders in South Sinai?
