Ghostly apparitions emerge from the morning fog.

Many are old bedsheets and tablecloths draped over the vegetable garden's best tomato plant or still-green pumpkins. (Just another week without a frost is all I ask!)

But the most impressive of these spooky sightings are the trees draped with masses of light gray, silken webbing. They're inhabited by a caterpillar called the fall webworm, which seems particularly abundant this year.

I suspect it's because our cool wet summer favored caterpillar survival and reproduction over that of their natural predators, various wasps for instance.

Those hairy webworms eating your leaves at the moment will live in the soil this winter as pupae, emerging next July as pure white moths. Then the cycle will begin again.

Unlike that spring pest, the Eastern tent caterpillar, the fall webworm isn't very harmful to the plants it feeds on. Unsightly perhaps, but the leaf feeding happens so late in the year that little damage is done to the health of the tree.

Why not think of the nests as early Halloween decorations? I know I've seen worse draped over trees.
