Browntail Moth Caterpillar Update
Tom Schmeelk, Maine Forest Service (MFS) FHM entomologist, reports that many browntail moth webs at his field sites in Lincoln and Cumberland county do not have evidence of caterpillar emergence although there are some that are active. He also reports caterpillars have developed to the 4th instar from Turner and Harpswell south to Portland. Caterpillars in the 4th instar are the first to have the irritating hairs that cause human health impacts. Stay tuned for updates!
