The adult is a moth somewhat resembling the codling moth. Theeggs are laid on the foliage about the first of July. The winter ispassed as a partly grown larva in a hibernaculum constructed for thepurpose. These hibernacula are very difficult for an inspector todetect and the insect is one that may readily be distil-uted on nurs-ery stock, scions, etc. The bud moth has been
