They are also called assassin bugs. They got the name kissing bug because they will bite your face and lips while you sleep. It isn't very common anymore for that to happen as most people treat their houses with spray. They are usually active at night, as they are noctural, but you can find them in dense bushes and brush during the day. Ugh. They are awful. The few times I was bit was when I was a teen, and was out hiking in the woods, and disturbed them in the brush. One got between my skin and shirt.
