Open AccessComplexity of Chemical Emissions Increases Concurrently with Sexual Maturity in Heliconius Butterflies
Pheromone communication is widespread among animals. Since it is often involved in mate choice, pheromone production is often tightly controlled. Although male sex pheromones (MSPs) and anti-aphrodisiacs have ...

Chemistry of the Androconial Secretion of the Ithomiine Butterfly Oleria onega
Ithomiine butterflies use pyrrolizidine alkaloids (PAs) as precursors for male pheromones, such as dihydropyrrolizines or lactones. In contrast to most other ithomiine genera, none of these compounds have ever...

Sexual Deception in the Eucera-Pollinated Ophrys leochroma: A Chemical Intermediate between Wasp- and Andrena-Pollinated Species
Ophrys flowers mimic sex pheromones of attractive females of their pollinators and attract males, which attempt to copulate with the flower and thereby pollinate it. Virgin females and or...
