Daily and seasonal timing systems in insects have usually been supposed to share similar mechanisms, because both rely in large measure on information from the daily light-dark cycle: daily clocks can ensure that activity coincides with the appropriate time of day, and seasonal time is indicated most reliably by daylength. However, several lines of evidence suggest that the systems are different. For example, receptor features, photosensitive pigments, clocks, and the effectors that mediate… CONTINUE READING
