The Hessian fly attacks wheat, barley, and rye. The Clover-Seed Midge lays its eggs in the young clover- heads W'here the larvoe or orange-colored nv^.ggots hatch out and do much damage. Then they fall to the ground and com- plete their changes, appearing as full-grown insects towards the latter part of summer, ready to do damage again to the second crop of clover. Where the midge is doing much damage it is evident that the pasturing off of the first crop of clover will tend to destroy the larvte. The first crop also may be cut early, when in full bloom, be- fore the first brood of maggots develop. A regular rotation of crops tends to keep in check these and many other injurious insects. Conclusions : 1. Insects are so-called because they are made up of sec- tions. There are three main i)arts, the head, the thorax or trunk, and the abdomen. The thorax and abdomen are also made up of sections (see illustrations). 2. The legs and wings of the adult or perfect insect are all attached to the Fig. 41.—Midge aiid Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original James, C.
