Hi there, 

Thank you for reaching out! This is our southwestern masked chafer, a common scarab beetle that we see here in the Grand Valley. These too can be pests of lawns but for the most part they are not considered a threat to anything. Adult beetles are pollinators and their larvae are c-shaped and very similar in appearance to the Japanese beetle.  This is luckily not the Japanese beetle,  that we recently detected in the area.

Please let me know if you have any additional questions,
