Wow. These guys can be found around my property in the summer. I had no idea these were stink bugs and despite handling them when I was younger, I've never smelled anything foul about them.

After some googling, the bug that I am familiar with as a stink bug is also known as a pinacate bug. These are up to an inch and a half long, and I never see more than two at a time. When I thought of 26k of these invading a house, I was shocked. Finding out this other beetle is also a stink bug was fun to learn. I could imagine an invasion of these.

These stink bugs are similar to box elder bugs, a kissing beetle, which can swarm when it warms up. These guys, I've had collect up in window sills. There are vastly more outside than in (they are flying around, gathering everywhere), but can be just an annoyance inside as they keep to windows.

These smaller stink bugs have an apparent vector of the Tree of Heaven, another invasive species that is actively combatted in my area. So it makes sense we would have the smaller stink bugs too. I was also surprised to read they were first documented in 1996 in America as I can recall these at least as early as 1990 or 1992. As a little kid, I would have to look out for them on the blackberries I picked out of my yard.
