Abstract

Adult males of Mygalopsis marki Bailey have 2 peak singing periods per year. This results from the emergence of adults in late spring/early summer and in early autumn. Adults emerging in summer were larger than those emerging in autumn. Summer and autumn adults did not represent successive generations. Samples from natural populations and rearing times in the laboratory indicated that summer adults were derived from eggs which hatched in December of the previous year while autumn adults were derived from eggs which hatched in late September or October of the previous year. Insects which emerge as adults in summer and autumn are referred to as different seasonal populations. There is potential for gene flow between the 2 seasonal populations, but the actual extent of gene exchange is not known.
