Three of our hives are all Italians, the other is a swarm hive with a fairly dark queen and mainly dark workers, but this hive is the pick of the bunch, so on the theory that it might be Caucasian, I'm about to requeen another one with a Caucasian to see how they go.
Put an order in with John Covey in Qld today - can't seem to find queens available for sale in Tas this year.
