Seek only identified it as a stink bug but couldn’t narrow it down further. I found very similar ones in Google images but nothing with those two yellow eyes on the back. Phila PA

Greetings,
This is an immature of a species of Pentatomidae - and I suspect it is Halyomorpha halys, the 'brown marmorated stink bug" - an invasive species from Asia. I can't be 100% sure, but the banded antennae and the apparent darker patches on the ventral side of the pronotum - metallic green if you can get a good look - help ID this species in the PA fauna.
Cheers!

Cheers! Bandrow Yes, the brown marmorated stink bug nymph was the one I found to be most similar but the patterns don’t match any of the stages. www.stopbmsb.org/stink-bug-basics/life-stages/ipm.ucanr.edu/pestalert/pabrownmarmorated.htmlThanx much.

There are also three black marks down the center of the underside that don’t match any of the images I saw either.

Despite not being an exact match, I suspect it could still be a marmorated. There were just ridiculous numbers of these in both VA and MA when we lived there, so I would wager they are well established in PA as well. They have kind of a unique size in my experience, where there are lots of smaller shield bugs and few larger, but not much of a similar size (at least in brown). That nymph you showed is already bigger than most of the smaller brown species and the bigger green species tend to be mostly green when they reach that size.
As a side note, in the falls we used to have fun shooting them off the window screens using a salt gun...good times.

What great memories lol. Thanks I will definitely keep looking for an exact match.

Greetings,
I missed those dark marks on the abdomen - I was trying too hard to see green on the prosternum! Go to BugGuide.net and scan the images of the genus Euschistus - some of them are very similar to Halyomorpha. Focus on those annulated antennae - not many eastern U.S. stink bugs have that coloration on the antennomeres.
Good hunting - and let us know if you nail down a match...
Cheers!
