Temporal transfer dynamics in honey bee workers. The black full line is the net transfer of proteinacious jelly by age, and the black dotted line is the net transfer of foraged foods by age. These patterns are typical during the favorable season. The red full line is the net transfer of jelly by a bee that develops into a diutinus worker at the onset of an unfavorable period. The diutinus workers also consume stored honey; thus, the red dotted line depicts this negative net transfer of foraged foods. As conditions improve, the diutinus workers transform into nurse bees and foragers. At this time, they develop the temporal transfer dynamics shown by the black lines.
