The Lichen Huntsman Spider, Pandercetes gracilis (also called the lichen spider), is a spider found in Queensland, Australia, as well as New Guinea, Maluku Islands, and Sulawesi.[1]

Description

The Lichen huntsman can vary in color amongst individuals, all of which are of the color of different species of lichen, but according to the Queensland Museum Inquiry Centre:

Spider colour is fixed at its previous moult. A slight exception being the abdomen with its much thinner walls which may change especially according to accumulated waste products or what it has eaten. So they can't change colour like a frog, gecko or squid. Some species of spiders that camouflage on tree bark have multiple colour forms however.

So far as is known, a lichen spider would not be selecting a background according to colour as these are like most (but not all) spiders in having poor vision. It is expected that they would have other ways of detecting a nice lichen-covered background to sit against however.

The Lichen huntman spider is one of the smallest members of the Huntsman family, usually growing to the size of a human fingernail.

Diet and hunting

The spider is known to hunt by ambush and then pounce when its prey comes within range. Its exceptional agility and speed, as well as its ability to squeeze into tight corners and camouflage, gives it a strong advantage both in capturing prey and evading predators.[2]

The Lichen huntsman spider is giving the upper edge on its ability to camouflage. Using its body to squeeze onto surfaces and blend it waits for its prey. The spider has 4 eyes on the front, two eyes on the top and two on the back of its head allowing it to have 360 vision in order to track not only the prey in front of it but behind it as well.
