Fall webworm—Hyphantria cunea
Larvae of the fall webworm are pale brown or gray caterpillars with long white hairs arising from black
and orange spots. There is only one generation per year.
Damage
Larvae feed in webbed colonies on ends of branches. Caterpillars are found eating foliage between the
leaf veins and forming silken tents on host trees. Damage occurs in mid to late summer.
Solutions
On small trees, cut out and destroy infested twigs. If necessary, Bacillus
thuringiensis or spinosad can be
applied to individual trees with a high-pressure spray when
evidence of caterpillars is first observed. |
