Small hostile mob that lives amongst the dust of the Petrified Forest.
Standard attack but on death will release an aoe cloud that blinds the player for a short while.
Drops to be worked out.

Personal idea for Dust Mites:
Dustmites are rather small and deal poor damage and no knockback. They have, say, 1 or 2 hearts of hp. Some Dust coverings act like pressure plates in a sense, and when stepped upon, a bunch of these will come out (say, 6-12?).

On their own, they pose little threat (think .5 hearts of damage?) but in a biome that has some other dangers around, they can be a ''lethal nuisance''.

This is a fun surprise (Erebus type of fun, that is) and fits with the biome theme of being ''trapped'' all around or rather dangerous to traverse if you don't pay attention.

Dyna Mite:

A variant of the Dust Mite that just immediately explodes into a Dust Cloud. This dust cloud is larger than usual. Accompanied by a nametag.
