The annual stinging tussock moth caterpillar invasion is under way

If you've stepped outside lately, you've probably noticed a smattering of curious caterpillars inching all over the place.

• Say hello to the stinging tussock moth caterpillar, which could be dark-bodied or light-bodied but is identified by tufts of hair-pencils — like little marshmallows — on its back.

What's happening: They hatched here aplenty in late February and are actively searching for crevices in which to pupate (eww).

• Be smart: This happens every year.

Why it matters: Those beautiful tufts of fuzz are barbed and the caterpillar has a venom gland, so petting these things, while appealing, can sting and leave a welt on your skin.
