Not illustrated. 1908 Excerpt: ... the potato beetle to such an extent that the in-1 sect makes up 9.05 percent of the subsistence of the entire number and nearly 35 percent of that of the individuals eating it. The significance of these figures will be better appreciated when it is considered that the potato beetle probably was not obtainable by many of the grosbeaks, and furthermore, that it is very unusual for birds to prey so extensively upon a single kind of insect, or even on the species collectively of a whole group. Such concentration of attack of a common bird upon a single species of insect, however numerous, can not but have a restraining influence on its numbers. The beetle is fed upon from May to September and both larvse and adults are devoured, 10 to 14 being found in single stomachs. By feeding upon the larvse the rosebreast directly benefits the potato plants, and by destroying adults the increase of the species is checked. - Am. Nat., IX, 1875, p. 375. -Trans. 111. Hort. Soc, 37 (1903), 1904, pp. 331-332. 0 U. S. Dept. Agr., Farmers' Bui. 54, 1904, p. 35. Although the potato beetle is the worst pest in the Chrysomelidse, this family contains other serious enemies of crops. The rosebreast feeds upon several of them, thereby further commending itself to our esteem. Both the small striped and the spotted cucumber beetles (fig. 26), which are abundant and injurious over much of the United States, are consumed. The importance of the bird's inroads upon one of these little black and yellow species, which in the larval stage is the destructive corn root-worm, is emphasized by the fact that no-direct method of combating the insect has yet been devised. Twelve grosbeaks fed upon these beetles, as many as 7 being found in a single stomach. Further evidence of the bird's st...Read Less
