Their bites feel like a pinch, and they leave a red mark, like a pinch. And they seem to love white/light colors. I've seen them in the house throughout the entire year, when they should have been long dead from the cold temps.
So the stinky, biting ones are the Asian beetles? The minute you touch them, the lay down the stinky stuff that you can see AND smell. I remember when we had a hideous invasion of them where there were thousands in the air, looking like a cloud. I remember having to run to the car when I needed to go anywhere. They get the automatic severe death penalty when they dare to get caught in my house. They didn't seem to care about southern exposures.
