Two Invasive Insects found in Minnesota 

The Minnesota Department of Agriculture reported that two new invasive insects were reported to the MDA’s Report a Pest Service. The two new invasive insects were reported by two separate homeowners. The two insects have been identified as the Elm Seed Bug and the Asiatic Garden Beetle. 

The elm seed bug has piercing sucking mouthparts and primarily feeds on elm seeds but can also feed on linden and oak. The bug is native to Europe and first appeared in the United States back in 2012. The bug has also been identified in Oregon, Washington and Utah. 

Adult elm seed bugs are about 1/3 inch long; they’re a dark rusty-red and black color. The underside of the insect is red. On the back behind the head, there is an upside-down black triangle set inside two rusty-red triangles. Next to the edges of the wings where the abdomen is exposed are alternating white and rusty red-black patches.

The Asiatic garden beetle is an invasive insect that feeds on over 100 hosts, including fruit, vegetables, perennials, and annuals. Asiatic garden beetles are about 3/8 inch long, are chestnut brown, and may have a slight iridescent sheen. The abdomen protrudes slightly from the wing covers. Adults emerge at night and fly actively when temperatures are above 70 degrees Fahrenheit. 

Since the two species are newly discovered in Minnesota, the MDA would like to better understand where these insects may be in the state. Residents can report suspected sightings of both insects to the MDA’s Report a Pest Line or call 1-888-545-6684. The MDA asks that people submit photos if they make an online report.
