摘要:
ABSTRACT.1. The colour of eggs laid by individualCoenonympha pamphilus(L.) (Lep., Satyridae) females changed over their lifespan. The first laid eggs were green, but after having laid about 100 eggs, females laid only yellow eggs.2. By following females in the field, or by capturing wild females, and noting the colour of their eggs, it was established that younger females showed higher oviposition rates and laid heavier eggs than older females.3. Hence, wildC.pamphilusfemales are unable to sustain a constant egg production by extracting amino acids or any other nutrients from nectar. We hypothesize that this is a general phenomenon in nectar feeding butterflies.4. The egg colour did not seem to match the colour of the substrate on which the female chose to deposit the egg.
