1. Pheromone production in the butterfly Pieris napi L
Abstract : Aphrodisiac and anti-aphrodisiac pheromone production and composition in the green-veined white butterfly Pieris napi L. were investigated.Aphrodisiac pheromone biosynthesis had different time constraints in butterflies from the diapausing and directly developing generations. READ MORE

2. The evolution of mating rates in Pieris napi
Abstract : In the green-veined white butterfly (Pieris napi), females obtain direct fitness benefits from mating multiply and studies have shown that fitness increases seemingly monotonically with number of matings. The reason is that at mating males transfer a large nutritious gift (a so called nuptial gift) to the females that the females use to increase both their fecundity and lifespan. READ MORE

3. Immunity & the butterfly : A functional genomic study of natural variation in immunity
Abstract : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. READ MORE

4. Effects of climate on phenological synchrony between butterflies and their host plants
Abstract : Shifts in species’ phenologies and phenological asynchronies between the interacting organisms have received a lot of attention in the context of climate change. Changes in temporal overlap between species, caused by phenological asynchrony, make species depending on one another become so separated in time that they can no longer interact. READ MORE
