Should this tiny foe ever become so troublesome as torequire a remedy, the best one suggested is that of carefullygathering and destroying the shrivelled fruit. No. 171.—The Grape-berry Moth. Eudemis botrana (Schiff.). This insect is an imported species, and has long been in-jurious to grape-culture in the south of Europe. The exactperiod of its introduction to America is not known, and it isonly within the past few years that attention has been calledto its ravages. When abundant, it is very destructive; insome instances it is said to have destroyed nearly fifty percent, of the crop. The young larvse are found injuring the grapes early inJuly, when the infested fruit shows a discolored spot wherethe larva has entered. (See Fig. 310, c.) When the grape Fig. is opened and the contents carefully examined, there willgenerally be found in the pulp a small larva, rather long andthin, and of a whitish-green color. Besides feeding on the ATTACKING THE FRUIT. 299 pulp, it sometimes eats portions of the seeds, and if tlie con-tents of a single berry are not sufficient, two, three, or moreare drawn together, as shown in the figure, and fastened with apatch of silk mixed with castings, when the larva travels fromone berry to another, eating into them and devouring their juicycontents. At this period its length is about an eighth of aninch or more; the head is black, and the next segment has ablackish shield covering most of its upper portion; the bodyis dull whitish or yellowish green. As it approaches maturity,it becomes darker in color, and when about one-fourth of aninch long is full grown. (See 6, Fig. 310.) The body is thendull green, with a reddish tinge, and a few short hairs, headyellowish green, shield on next
