Hi all
We haven't discussed this in a while, but I stumbled on this, which touches upon the relation between colony activity and photoperiods.
An automated system is described for continuous recording of sound emission by honeybee (Apis mellifera)
colonies as a measure of activity. Colonies were monitored throughout the year. Output of sound, with respect
to both amplitude and duration, was greatest in summer, declined to a low level in autumn, and ceased by
December, resuming in mid-January. Colonies from which light was excluded during the winter re-.established
their normal seasonal pattern at the same time as those exposed to the natural photoperiod.
