Actually, the wild hive that you captured is no wilder than any other managed hives in the area.
Where ever honey bee hives are present, there will be hollow trees or old shed walls that will become homes from swarms cast.
The genus is always apis, and the species: melifera, the race is whatever the beekeeper last purchaced or bred.
To identify the race, grab a senior beekeeper in your area and give a look.
I have exactly ONE less dead-out than you.
That makes my opinion beyond dispute!
