[Illustration: FIG. 3. RED, OR HORSE-ANT (Formica rufa.) a, male; b, female, winged; c, worker.]
The common ants (Fig. 3), the study of which in their native haunts is a matter of no great difficulty, and one which will fully reward the seeking mind, like the termites, possess three grades of individuals. In a single ant’s nest more than One female may be found, the ants differing from the bees in this respect; and in the nests of some species of ants there are apparently “soldiers” resembling the military termites in the possession of large heads and well-developed jaws. Very amazing differences are to be perceived amongst the various species of ants. Differences in size are of common occurrence, but naturalists have actually succeeded in classifying ants in a general way, by differences in manner and disposition. We know, for example, that the horse-ant (Formica rufa, Fig. 3) has little individual intelligence, but is extremely socialistic, and moves and acts en masse with precision and tact. Another species (F. fusca) is timid and retiring. F. pratensis is a revengeful creature, since it “worries” its fallen foes; F. cinerea is bold and audacious; others are termed “thieves” and “cowards”; some are phlegmatic; and to complete the list of failings and traits which are human enough in character, one species is said to present an invariable greediness as its prevailing characteristic. The common ants resemble the termites in the general details of their life. We see in
