Elasmucha lateralis on Aug 27, 2019

Originally reported as Stink Bugs (family Pentatomidae)

Submitter does not have a specimen
EDRR Status: No Response/Action Required

Description of specimen

See photographs of aggregation of orange and brown/black true bug nymphs on the underside of an alder leaf. They don't really seem to match any photos I have in my (meager) bug identification resources - but there's some resemblance to the photo of Brown Marmorated Stink Bug nymphs in the Stink Bugs of Oregon pamphlet produced by the Oregon Dept of Agriculture. Just want some verification of whether it's BMSB, or if another identification could be made. Thanks!

Commentary

Dear Karen, hard to say if they are BMSB or not. If we could zoom in on the antennae this would help. If the antennae show some, what I call, Adidas rings, they would be BMSB. I was more intrigued by the cater pillow. Seems like a tiger moth. Sorry, that I can't give you a better answer. Helmuth Rogg

On second thought: One of my colleagues said that they look like Elasmucha lateralis, which is a native Pentatomid known from alder. Cheers, Helmuth
