ENTOMOLOGY FOR BEGINNERS.: MIGRATORY INSECTS
Published online by Cambridge University Press: 31 May 2012
Extract
The migratory instinct, common to so many species of birds, and even of mammalia, is also exhibited by many species of insects. In the case of birds and animals it has mostly to do with variations of climate, or the necessity of suitably providing for the raising of their young; in the case of insects the causes of migrations are not so evident, and observation is required in order to decide the point, if, indeed, it can be decided at all.
