Economic entomology for the farmer Economic entomology for the farmer and fruit-grower economicentomolo01smit Year: 1906 3i6 A/V ECONOMIC ENTOMOLOGY. A very curious species is the Gallcria melonella^ or '' bee- moth,' which infests beehives and feeds upon wax. A brood of these caterpillars sometimes invade a hive and bore into the wax out of sight of the bees, frequently demoralizing them to such an extent that they abandon their home, seeming unable to find a way of dealing with this kind of enemy. In the recent types of hives there is little opportunity for these pests to estab- lish themselves, and if the bee-keeper is on the alert, he will at once perceive any such invasion. It is easy then, by transferring and cleaning out the infested frames, to save the swarm. The moths are rather curious creatures, mottled and streaked on the fore-wings, the outer margins of which are also a little excavated. Under the general term Cra??ibids we may describe a series of species with slender body, narrow, rather squarely cut off fore- wings, and broad hind wings. When at rest the wings are rolled Fig. 362. Crambus vulvivagellus.—a, larva; b, over-, and c, underground tube and cocoon ; rf, e, f, moths with wings spread and at rest; g, an egg much enlarged. up or folded closely, giving the insect a little the appearance of a tiny cylinder. The head is small, not at all retracted, and usually furnished with very long palpi that project straight out like a snout ; as a whole, resembling somewhat one of the groups of the deltoid Noctuids. The fore-wings are generally white or yellow- ish, quite frequently streaked or spotted with silver and gold ;
