### Identification The **Lichen Huntsman (*Pandercetes gracilis*)** is a masterclass in cryptic evolution. Measuring roughly 20–30mm in body length with a much wider leg span, its silhouette is remarkably flat. Its coloration is its most striking feature: a mottled "salt-and-pepper" palette of mint greens, ashy greys, and charcoal blacks that perfectly mimic the crustose lichens of its environment. To distinguish it from other Sparassidae, look closely at the legs. *P. gracilis* possesses unique, lateral fringes of long hairs (setae) along its legs. These fringes are not just for show; they blur the spider's outline against the bark, making it nearly impossible to tell where the spider ends and the tree begins.
### Habitat & Range This species is a specialist of the humid tropics, primarily found in the rainforests of Northern Queensland, Australia, as well as parts of New Guinea and Southeast Asia. It is strictly arboreal, favoring large, mature tree trunks—particularly those heavily encrusted with moss and lichen. You won't find these in your garden shed; they prefer the high-humidity microclimates of primary and secondary forests, often at lower to mid-elevations.
### Behaviour By day, the Lichen Huntsman is a "frozen" statue. It presses its laterigrade (crab-like) legs flush against the bark, remaining motionless for hours to avoid the keen eyes of birds. By night, it becomes a high-speed pursuit predator. Unlike most spiders, it does not use a web to catch prey. Instead, it relies on its extraordinary peripheral vision and sensitivity to vibrations. Observers may notice that when disturbed, it doesn't just run; it "vanishes" with a burst of speed so rapid the human eye can barely track it.
### Diet An opportunistic carnivore, its diet consists mainly of nocturnal insects like moths, crickets, and beetles. It is a "sit-and-wait" ambush hunter. When an insect wanders within range, the huntsman lunges with explosive force, pinning the prey with its powerful chelicerae and delivering a quick-acting venom.
### Fascinating Fact The Lichen Huntsman doesn't just hide with color; it hides with physics. The specialized hair fringes on its legs are angled so precisely that they eliminate the "telltale shadow" typically cast by a spider’s body. By softening the transition between its legs and the bark, it effectively deletes its own 3D silhouette, rendering it invisible even in direct light.
