An invasive moth that can damage hardwood and fruit trees has been spreading in Maine. State officials are asking residents to be on the lookout for winter moths, which have spread into Maine from southern New England, where they have caused widespread damage. The moth was first detected along the Maine coast in 2006 and has been spotted in the past year in Harpswell and Vinalhaven. The Maine Sunday Telegram, says state officials have reported 13 sightings of moths in Cape Elizabeth, as well as scattered reports from Scarborough, South Portland, Portland, Falmouth, Woolwich, Westport Island and Brunswick. Residents are being asked to keep an eye out for the moths, which are likely to be flying in swarms this time of year, and capture some specimens if they can.
