Not illustrated. 1880 Excerpt: ...day of its existence, counting from the time the egg was laid, it comes forth a perfect winged insect. The cocoon is left behind and forms a closely attached and exact lining to the cell in which it was spun. By this means the breeding-cells become smaller, and their partitions stronger, the oftener they change their tenants, and may become so much diminished in size as not to admit of the perfect development of full-sized bees. Such are the respective stages of the working-bee. Those of the royal cell are as follows: she passes three days in the egg, and is five a worm; the workers then close her cell, and she immediately begins spinning her cocoon, which occupies her twenty-four hours; in the tenth and eleventh days and part of the twelfth, as if exhausted by her labour, she remains in complete repose. Then she passes four days and part of the fifth as a nymph. It is on the sixteenth day, therefore, that the perfect state of queen is attained. The drone passes three days in the egg, and six and a-half as a worm, and changes into a perfect insect on the twenty-fourth or twenty-fifth day after the egg is laid. The development of each insect proceeds more slowly when the colonies are weak or the air cool. Dr. Hunter has observed that the eggs, worms, or nymphs all require a heat above 700 Fah. for their evolution. Both drones and workers, on emerging from the cell, are at first grey, soft, and comparatively helpless, so that some time elapses before they take wing. The workers and drones spin complete cocoons, or inclose themselves on every side, while the royal larvae construct only imperfect cocoons, open behind, and enveloping only the head, thorax, and first ring of the abdomen, and Huber concludes, without hesitation, that the final cause of this is, th...
