Pupae January I I O November Fig. 5. Summary graph of life cycles of Chauliodes rastricornis (bottom), and C. pectinicornis (top), from Greenbottom Swamp, Cabell County, West Virginia. Larval head width means are plotted against months of the year. Straight lines = emergence periods of pupae and adults. December in Florida, and specimens of C. rastricornis in West Virginia were only found on 2 June (Tarter et al. 1977). The C. rastricornis pupae reared in our laboratory transformed into adults between 29 April and 13 May, and the C. pectinicornis emerged between 10 July and 27 August. This separation of emergence times helps keep these two species from interbreeding. No mating, ovip- ositing, eating, or drinking was observed. Brimley (1908) reported rearing larval Chauliodes caught on 4 April 1906 to adults, which first emerged 21 April and continued trans- forming until 20 May 1906. Parfin (1952) recorded rearing C. rastricor- nis, which first emerged on 5 June and lived approximately six days on honey and water. The sex ratio of 77 C. rastricornis captured by the light traps was 5 males: 1 female, and a chi-square test indicated a significant difference ( level). Since all five C. pectinicornis trapped were males, a chi- square value was not calculated. Adult C. rastricornis, reared from pupae, showed a fecundity range of 922 to 1612 eggs (x = 1166) per female, but light-trapped females of the same species contained between 8 and 637 eggs (x = 388).
