ST. PAUL, MINN. – The Minnesota Department of Agriculture is confirming the appearance of a new invasive species that attacks elm trees.
The agency says elm zigzag sawflies have been found on the Twins Cities campus of the University of Minnesota.
The insect is native to Asia and was first found in the U-S in 2021. It was named because of the distinctive zig-zag pattern it leaves on elm leaves.
The insect can harm elm trees, though state ag officials say the full impact is still unknown.
