August 10 only two pupae were collected, so that it can be safely assumed that all the individuals taken after this date belonged to the second or overwintering brood. FIRST-BROOD EMERGENCE v. OVERWINTERING EMERGENCE, 1911. From band records collected in 1911 (see Table LIV) 774 larvae and pupae were taken. Some of these, from the first collections, were placed in vials for individual pupal records, while the remainder were placed in jars for adult emergence records. Those placed in the vials were all of the first-brood larvae and only a very small percentage overwintered. The latter collections—both consisting of first-brood and second-brood larvae—resulted in an emergence of first-brood moths of about 18 per cent. Only 157 moths emerged from these collections, although a considerable number of pupae died in their.
