Adult Emergence in Two Univoltine \u3ci\u3eCallosamia Promethea\u3c/i\u3e Populations: Preponderance of the Early Emerging Morph in the North and of the Late Emerging Morph in the South (Lepidoptera: Saturniidae)

Callosamia promethea is common on wild black cherry, Prunus serafina, at the University of Michigan Biological Station in northern lower Michigan. In this area the early emerging morph is preponderant, while to the south in northern Indiana, the late emerging morph is preponderant

Diapause and Emergence Patterns in Univoltine and Bivol Tine Populations of Promethea (Lepidoptera: Saturniidae)

Data are presented on the diapause and the seasonal emergence patterns of the adults of a univoltine Callosamia promethea population from northern Indiana and a partially bivoltine population from central Illinois. At Urbana, Illinois, the median emergence date of adults from overwintering Illinois pupae was about a month earlier than that of adults from overwintering Indiana pupae. Illinois samples had a much longer emergence period than Indiana samples. Indiana samples showed a slight tendency toward a bimodal emergence pattern, a few individuals emerging in late May and the rest emerging as a tightly synchronized group from late June to mid-July. Early emerging lIIinois moths produced mostly non.diapausing progeny, but the proportion of diapausing progeny increased as the season progressed. Some females produced both diapausing and non· diapausing progeny. Adults from non-diapausing pupae from early August to early September

Longevity and Weight Loss of Free-flying Male Cecropia Moths, \u3ci\u3eHyalophora Cecropia\u3c/i\u3e (Lepidoptera: Saturniidae)

During their spring flight season, free-ranging male cecropia moths lived a maximum of 12 days (one of 124 recaptured moths of 387 released moths). The number of survivors declined precipitiously after day five; five to seven days is probably the usual life span. The recaptured moths did not have different initial weights than those that were not recaptured. The larger the moth the more absolute weight it lost and the faster it lost weight during the first few days. A moth lost about 20% of its weight during the first night of flight and accumulated about a 40% weight loss during the remainder of its life

Melanistic Males of \u3ci\u3eCallosamia Promethea\u3c/i\u3e (Lepidoptera: Saturniidae)

(excerpt) During the summer of 1983 seven melanistic male promethea moths appeared among several hundred males that emerged from cocoons we were holding in the laboratory
