Children are often fascinated with this commonest of all insects. Not mighty in size, but mighty in resourcefulness and industry, the ant has crawled the earth since prehistoric times. It has dwelt in rain forest tree trunks and in acorns of oak trees, beneath logs, and under sidewalks. It has protected forests by capturing insects, has cleared weeds away from acacia trees, and by growing gardens has released important nutrients into the soil. Seed-lifters, dirt-diggers, social beings, ants have the most advanced brain of all insects! So watch where you step, especially on a warm day. A small but mighty ant may be underfoot.
