Before you report a possible gypsy moth find

Many native, less damaging moths that look similar to gypsy moths, are present in Missouri and do not need to be reported.  Consult the gypsy moth signs and symptoms page before reporting.  Early detection is useful only when the problem is contained and eradicated. To help with this effort:

  • On caterpillars, especially look for the five pairs of blue warts and six pairs of red warts on their backs.
  • Call the Missouri Department of Conservation toll-free at 866-716-9974.
  • Send photos if possible. Take photographs of the entire tree, a close-up of leaves, and any other symptoms. Email digital photos and contact information to
