 I mean, it would be exceedingly rare for it to happen, but it is possible. Just like I believe Debbie from Ocean Springs chimed in and said that she found a brown widow, not a black widow, a brown widow, and of course killed it. But a brown widow is considered at the same level of lethality as far as the venom of a black widow. They just don't bite as often and they don't inject as much venom.
