| Fall
Webworm
By CONNIE MERTZ
There is no
mistaking the fall webworm's maze of netting while driving along
or viewing it from a vista. Backlighting from the sun turns them
into a quite a masterpiece. Living in colonies, the fall webworm
starts webbing at the tips of branches and works its way down, enclosing
only those leaves it will consume.
The fall webworm
is not to be confused with the tent caterpillar which is common
in spring. This leaf-eater hatches in summer. The eggs are usually
attached to the underside of their host plants. The larvae never
leaves the immediate area. Colonies of webworms can be very destructive
to such trees as willow, ash, hickory, maple, oak, walnut and apple,
but usually trees recover.
Once fall arrives,
after several molts, they leave the web to spin cocoons in the crevices
of the tree or in leaf litter. They will remain in this stage during
the winter months. In May, the adult web worms hatch, mate and lay
eggs propagating their species.
The moth of
the webworm is about 1.5 inches, white with brown or black spots
on the forewing. Unfortunately, this pest is common throughout the
United States.
