Caterpillar 3/4-2" long devastates rose bush in spring! #629020

Asked April 29, 2020, 4:44 PM EDT

Check out the overnight devastation of my rose bush this week (April 26, 2020). Nothing visible during the day. But at night I caught the pest. It is gray with chevrons on the back near the head. Some sort of armyworm? I bet it came in on the horse manure I threw down last fall. The manure came from a farm in Hood River. Thanks.

Hi!

I would consider this "worm" a cutworm larva of the Noctuidae family of moths.  Possibly of the genus Spodoptera, though I cannot be 100% correct from just a photo.  Hope this helps! 

Best,
