STRATEGIES FOR EGG PRODUCTION [PDF]
Evolution, 1974 The view that egg production is adapted to counter, and thus provides a measure of, the relative hostility of the environment in which organsms must live has been expressed repeatedly (e.g., Stresemann, 1934; Rensch, 1938; Moreau, 1944; Schmalhausen, 1949; Skutch, 1949, 1967; Cole, 1954; and Smith, 1954).

Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]
, 2009 During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...
