Tliese larva' burrow into the i'ruitlets and eat out large ca\'ities, often attacking apples when they are no hirger than cob nuts. Each of these large irregular cliambers communicates ^\•ith the exterior by a small round which is usually noticed on the side or near the eye of the apple, fhit of this opening one fre(iuently finds " frass" and much moisture exuding.
