Looks like a stink bug nymph. Exactly which stink bug I am unsure of because Norton's search sucks (if you think Google is bad about featuring paid sites, Norton's is worse, they tend to only show sites that sell stuff - but they are "verified safe" sites. Finding actual information is not anywhere at the top 90% of the list. Doesn't help that stink bugs and their nymphs are not uniform in how their coloring is dispersed, even in a given variety. It could possibly be a green stink bug nymph. It looks like it has red shoulders in your pic, so that is what I'm gong with
99 Has been on the warpath since we began seeing them. Not many survivors once she grabs the flyswatter! Anyway, I don't think they are a stink bug (thankfully) as there is absolutely no residual smell from their lifeless squashed carcasses....... But they do look like the images bogieb posted.......
after Googling, I found that there are people that dont' think that stink bugs stink, they smell more like cilantro or mown hay fields. Since I am not a fan of cilantro - and it isn't overpowering. IDK, I only know what Google tells me. You can send a picture to your state extension and they would be able to identify for sure. If you do that, please report back.
Cilantro tastes so unpleasant to me, it's like when you accidently get tinfoil in you mouth. We don't have stink bugs here, but stink beetles (and I find it overpowering), just like normal black beetle but same result as bug, it smells metallic to me like cilantro tastes to me. To boot my migraine aura is.......metallic smell. I had a doosey a week + ago. It was after dark, so after "do you smell that stink beetle? " "no", I spent the next several minutes looking around for a smooshed beelte with phone flashlight without success. Duh, there was not beetle, it was aura.
