Bug identification #803817
Asked July 30, 2022, 6:58 PM EDT
Initially, I found these around my back porch. We identified them as elm seed bugs based on environment, photo and behavior. Literature mentioned they are drawn indoors in hot weather, which we have had.
A week or so later, I noticed the same bugs had infested my cherry tree, but according to everything I've found online, elm seed bugs aren't at all interested in fruit trees.
I was able to find photo examples of an infestation that is almost identical to what is in my cherry tree, but the insect was a brown marmorated stink bug. These definitely aren't that. They don't stink and don't have the body shape or markings.
Any suggestions?

And here is a link where a person found elm seed bugs on his apple tree...

It seems unlikely they will cause you any problems, other than being a nuisance.
Hope that helps!
