Economic entomology for the farmer Economic entomology for the economicentomolo00smit_0 Year: 1896 THE INSECT WORLD. 411 Fig. 470. \\\ \ small cells, each containing a supply of food sufficient for a single larva. The mother bee constructs a cell, fills it with a mixture of pollen and honey, and lays an egg in it. Then she closes up the chamber, and her work as to this particular larv^a is com- pleted. When the egg hatches, the larva finds a food supply im- mediately at hand sufficient to bring it to maturity. When it is fully grown it changes to a pupa, and eventually to an adult, which then makes its way from the earth- en home into the sunlight. The mother bee having completed one cell, at once begins the construc- tion of another, and thus the work is continued until the supply of eggs is exhausted. The open face of sand- or clay-banks is a favorite place for these insects, and sometimes they build their nests together in great numbers. The long-tongued bees are so called because the ligula or glossa is extended into a flexible ribbon- like structure, ringed but not seg- mented, set with circles of long hair, and frequently tipped with a little button-like structure. This enables the insect to reach the honey in deep flowers like the clovers, and in fact there are only certain bumble-bees with a tongue long enough to reach the nectaries of the red clover flowers ; hence they are entirely dependent upon these for pollination. Destroy the bumble-bees, and no red clover-seed can be obtained. It is a suggestive fact that in many localities where ruthless war is waged
