It's that time of year again in Charlotte, NC. Temperatures are rising and trees are blooming which means little green worms, otherwise known as Cankerworms are about to make their appearance. If you've walked the streets lined with trees in Myers Park, taken a neighborhood stroll in the Dilworth Community, or enjoyed a day at the park in Elizabeth, you've more than likely spotted little worms hanging from white silk threads or clustered together in a white caccoon.
The fall cankerworm is native to North America and Charlotte, NC is known to have severe cankerworm infestations. The cankerworm has a four-stage life: egg, pupa, larva, and adult; after mating in December, the female moths crawl up trees to lay eggs on twigs and small branches. As leaves come out in the spring the eggs hatch leaving some caterpillars to feed on the leaves. Cankerworms on their own typically do not kill trees; however, repeated defoliation weakens trees leaving them susceptible to other stresses.
