Sends a preliminary reply to CD’s query [5890]. Ten males to one female among captured micro-Lepidoptera. Six females to four or five males in those he has bred. HTS is aware this is diametrically opposed to information from [Alexander] Wallace and Bates, but the true proportion of sexes can only be ascertained by breeding.
Protective coloration in butterflies.
[Alexander] Wallace’s suggestion that collecting larger larvae of females accounts for error in counting proportion of sexes.
