Sort of? Uh...Not so great at the concept art thing.
Smoke Spiders aren't really spiders of course, they're more like a sub-species of ...something else? They're black and spindly and chitinous and smell like wood fires.
Their skin ashes away at the touch and they 'run' on a 'core' of gently smoldering heat in their chest. Extra limbs are willed into and out of existence, floating around them and loosely attached to the smoke around them.

Do they still eat bugs? Are fireflies a delicacy for them?
