Extract from Émile Blanchard’s Metamorphoses, moeurs et instincts des insectes [1868], on attraction of males by female Lepidoptera, and possible explanation.
Has tried using dealers’ price-lists as a guide to sex ratios in Lepidoptera; finds numerous cases in which the sexes bring different prices and in virtually all of them the males are cheaper. This seems to confirm the impression of the field collectors.
Wishes RT good luck with natural history in S. Africa.
