To H. T. Stainton   2 March [1868]

Summary

Thanks HTS for his valuable information. Hopes to arrive at probable answer to question of proportion of males to females in the progeny of butterflies bred in domestication.

On courtship of butterflies, CD believes something more than chance is involved in determining which male is successful.

From H. T. Stainton   20 February 1868

Summary

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.
