Gypsy Moths Can Defoliate Your Trees

By Randy Sample

June 2, 2019


Gypsy Moth defoliate trees and create an added stress which can leave trees vulnerable to disease and other pest infestations.  This will lead to the death of the tree.

The Gypsy moth is known to feed on hundreds of woody plant species.

Do you have any of these trees?

These are the preferred species of the gypsy moth:

  • Oak
  • Aspen
  • Willow
  • Linden
  • Hawthorne
  • Apple
  • alder

What about these less preferred species?

These less preferred hosts are usually fed upon when gypsy moth populations are high and preferred species become scarce.  

  • Elma
  • Maple
  • Hickory
  • Beech
  • hemlock
  • Pine
  • Spruce
  • Cedar
  • Sassafras

The Lifecycle of the Gypsy Moth

The caterpillars have been slow to emerge this spring due to below average temperatures and rainfall.  As the weather warms up the eggs begin to hatch. These caterpillars will slowly make their way up to the leaves where they will feed on foliage night and day. When they are half grown they will then usually feed at night time.  Usually by mid-June to early July these caterpillars will reach maturity and pupation will take place and they become Gypsy moths. 

local history of the gypsy moth

The gypsy moth was first introduced to the US in the 1860’S and is believed to have originated in the Boston area.  Since that time the range of gypsy moth has continued to spread. This most recent outbreak in Western MA began in 2015.  The towns that have been primarily affected are: Belchertown, Granby, Ludlow, Wilbraham, Monson and East Longmeadow.
