Weird. Black widows are larger, stronger and much more venomous than brown widows. Yet the brown widows are more aggressive and fecund so they will win and the black widows will go extinct.
Something Americans better take to heart and fast.
I had a Tarantula in the yard one Fall day.
A couple of days later it was wrapped up in the Black Widow web in my storage shed.
I was sad. Expected to see that Tarantula a few more times during its migration.
