Concealed Phases in the Metamorphosis of Insects


WORK on the biology of insects is becoming more exact than formerly. Attempts are more frequently made to control with precision some of the physical factors, particularly temperature and humidity ; and it is not uncommon to find that the mean and standard deviation are given of the temperature and duration of the various instars. In some instances, even the wave-length of the light to which the insects were exposed during the experiment is stated. This increasing accuracy has not, curiously enough, resulted in a closer examination of some of the assumptions that are universally made.
