do actually exist that fire cannot destroy; for this creature, so the story goes, not only walks through the fire but puts it out in doing so. On the river Hypanis in the Cimmerian Bosphorus, about the time of the summer solstice, there are brought down towards the sea by the stream what look like little sacks rather bigger than grapes, out of which at their bursting issues a winged quadruped. The insect lives and flies about until the evening, but as the sun goes down it pines away, and dies at sunset having lived just one day, from which circumstance it is called the ephemeron. As a rule, insects that come from caterpillars and grubs are held at first by filaments resembling the threads of a spider’s web. Such is the mode of generation of the insects above enumerated. but if the latter impregnation takes placeduring the change of the yellow < div id=“section87” class=“section” title=“20”> 20 The wasps that are nicknamed ‘the ichneumons’ (or hunters), less in size, by the way, than the ordinary wasp, kill spiders and carry off the dead bodies to a wall or some such place with a hole in it; this hole they smear over with mud and lay their grubs inside it, and from the grubs come the hunter-wasps. Some of the coleoptera and of the small and nameless insects make small holes or cells of mud on a wall or on a grave-stone, and there deposit their grubs. With insects, as a general rule, the time of generation from its commencement to its completion comprises three or four weeks. With grubs and grub-like creatures the time is usually three weeks, and in the oviparous insects as a rule four. But, in the case of oviparous insects, the egg-formation comes at the close of seven days from copulation, and during the remaining three weeks the parent broods over and hatches its young; i.e. where this is the result of copulation, as in the case of the spider and its congeners. As a rule, the transformations take place in intervals of three or four days, corresponding to the lengths of interval at which the crises recur in intermittent fevers. So much for the generation of insects. Their death is due to the shrivelling of their organs, just as the larger animals die of old age. Winged insects die in autumn from the shrinking of their wings. The myops dies from dropsy in the eyes. 1082
