• The ancient belief that bees were generated in decaying carcases of cattle, etc. (c.t., Judges xiv., 12 — 18, and Virgil's 

 Fourth Georgic). The facts ate, that the fly Eristalis tenax resembles the honey-bee, and that its larvae are carrion-eaters ; 

 hence when they have finished a carcase they pupate beneath the skin and dibris that remain, emerging eventually as perfect 

 insects in crowds which were mistaken for swarms of bees.
