Description: In termites, differentiation plasticity in undifferentiated Reticulitermes progresses with growth stages from larvae to workers, which may then differentiate into soldiers, winged nymphs, or neotenics. Although studies have been done on seasonality of the termite life cycle, data appears to vary from location to location. Reticulitermes populations in Wisconsin appear to behave slightly differently in terms of colony formation and differentiation than in other parts of the continent. Timing of differentiation, feeding, and foraging behavior show some specific trends in Wisconsin termite colonies, probably linked to climatic limitations. Peak egg laying is seen in April to May, followed by a peak in emergence of larvae in May, with primary growth and differentiation occurring in June and July. Growth, feeding, and differentiation all drop off around late July to early August, reflecting an overwintering population of mainly workers.
