Abstract

The first matings of males resulted in the transfer of large spermatophores, while subsequent matings resulted in smaller and eventually no spermatophore. The transfer of a spermatophore was not required to produce a normal number of fertile eggs. Some young males inseminated two females within 24 hours and regardless of whether or not a spermatophore was formed the number of resulting progeny was normal. Thus males were found to be capable of inseminating more females than the yield of spermatophores obtained by dissecting females indicated.

Virgin females increased in attractiveness with age at least until their fifth day.
