The two sibling species D. /melanogaster and D. simulans adopt different overwintering strategies in northern border areas situated in France. If the winter is mild, both species reappear in early spring to refound the population. If the winter is cold, with several weeks of temperatures below 0 °C, D. melanogaster leave their shelters in April whereas D. simulans, which do not use shelters, reappear in late June, probably after returning from further south. Here, we tried to identify life… CONTINUE READING
