Life History.

This moth is a pretty little insect belonging to the family Tortricidæ. It is dusky grey in colour, with wings slightly tipped with white. It flies in the evening, and may often be seen in large numbers upon tares and sainfoin, though it has not been ascertained actually that it attacks these plants in the same way as peas. It places two or three eggs upon the young page 64 pods before the calices have fallen. From these pale green, rather inclining to yellow, caterpillars come and pierce their way into the pods, and then bore into the tender peas. They are about four lines long, or a little over a quarter of an inch, when full grown, having several pairs of legs. When the peas get hard the caterpillars fall to the ground, and getting below the surface enwrap themselves in silken cocoons, in which they remain until they change to pupæ in the spring. Some of the caterpillars remain in the pods and haulm and are carried with the peas.
