Tlie adults are extremely tiniiil and hdl at the least vil)ration. Of those fallen upon the ground, very few â crawl up the trunk so as to regain the brandies. Xnw what becomes of the others unless tliey fly Ijack to the tree or to other trees '. Although the females do not readily take w'ing, yet they undoubtedly do fly from the ground into the branches, especially on warm, sunny days. 1 am sure that the females fly more than we imagine. In any case the recommended grease - banding will not catch them, which it might do if they crawled up the trunks of tlie trees as has been averred by some people, not naturalists. Copula- tion \indoubtedly takes place upon â¢the branches. The female de[)Osits her ew's in the blossom liuds before thev open. As soon as the blossom conrmences to expand she leaves off ovipositing, as the larva' could not live in an open bhjssom. Thus it will be seen that cold, damp weather, in spring, especially nights with frost, keeping ))ack the buds, extends o\-er a greater length of time the egg-laying period of the female. A single ovum is deposited in each blossom, lint several possibly in a lilossom fiud. The act of oviposition takes some time, usually at least three- (puirters of an hour, so that a single female cannot la
