Excerpt from An Introduction to Entomology, Vol. 2 of 4: Or Elements of the Natural History of Insects With respect to the duration of the societies of insects, some last only during their first or larva state; and are occasionally even restricted to its earliest period - some again only associate in their perfect or imago state; while with others, the proper societies for instance, the asso ciation is for life. But if I divide societies of insects into perfect and imperfect, it will, I think, enable me to give you a clearer and better view of the subject. By perfect societies I mean those that are associated in all their states, live in a common habitation, and unite their la bours to promote a common object - and by imperfect societies, those that are either associated during part of their existence only, or else do not dwell in a common habitation, nor unite their labours to promote a common object. In the present letter I shall confine myself to giving you some account of imperfect societies. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
