State agriculture officials say an invasive insect has now been confirmed in St. Clair County, marking the first time the elm zigzag sawfly has been found in Michigan. The pest feeds on elm tree leaves, leaving a distinctive zigzag pattern and sometimes causing heavy defoliation, though healthy trees can recover. Officials stress the insect is not a threat to people or animals, but they are asking residents to report sightings through the MISIN app and take steps like cleaning gear and avoiding moving firewood to help limit its spread.
