Unless those swarms usurp an established colony. Evolutionarily, it would
be highly advantageous, since a suicide squad of an aging queen and a small
number of protective workers could take over an established colony already
possessing winter stores, and thus pass their genetics to the next
generation.
The observed occurrence of a September peak in swarming, Wyatt Mangum's
observations, plus my own observations over the years in Calif, all appear
to me to support my hypothesis that late-season usurpation swarming is not
only an Africanized bee trait, but an established trait of the North
American population of European bees.
