Hi there,
When taking our AC out today we found two of these bugs. i find them very interesting. I'd love to know what they are.

They are relatively slow crawlers, about 2-2.5cm I'd guess. I am trying to figure out if that is a probiscus I see under them. their antenna have little white stripes on them near the end. when one dropped a short height it tried to fly, but otherwise made no use of their wings. It might be the cool weather as it is raining and 12 degrees C today.

Should I let these guys go?

EDIT: location is Southern Ontario

Ah apologies, it is possible this picture is of one who is a bit injured. It was wedged in a tough spot in the vent. It looks like it's backside could have suffered.

These are Hemipteran bugs, and that is a sucking proboscis you can see on the underside. Some species are plant piercing, others feed on other insects.

Probably someone in N America can ID these more accurately than I can.

I'm no expert, but I believe these are at least a visual match to Halyomorpha halys, otherwise known as the brown marmorated stink bug. This (invasive) species has gained some notoriety in North America due to its status as an agriculturally significant pest: It is native to East Asia, but was first collected in Pennsylvania in 1998. Populations have since thrived and expanded their ranges aggressively, and it is now one of the most commonly-sighted Pentatomids, at least in the United States.
