At home in the Southwest, this Darkling Beetle is tiny and fuzzy. The hairs may help deter predators from eating it, and its size makes it a smaller target. The beetle feeds on Russian thistle, wild onions, and salt grass growing in the arid environment. They are most active in spring, coming out of overwintering, and then again in late autumn as they prepare for the next winter. Occasionally on warm winter days, they may venture out from their shelter.
Look for this species walking along the ground, keeping in mind that the beetle never gets much bigger than a pinky fingernail. The spray of hairs on its back may give it a bit more presence, but a keen eye may be needed to see one, especially if it isn’t moving.
