- ... More than 300 samples of Macrolepidoptera have been collected over 24 years at a site in southern England on field courses run for university students. The samples were taken in mercury vapour light traps. They show that numbers have fluctuated markedly between periods of high abundance and periods of low abundance. Species richness in the samples is strongly affected by abundance. Evenness of dis ...

- ... Pyrrolizidine alkaloids (PAs) often serve as chemical mediators of plant-herbivore-predator interactions. Butterflies (Danainae and Ithomiinae) and moths (Arctiidae) usually acquire PAs from plant sources (larval host plants, flowers or withered leaves visited by adults--pharmacophagy) and thereby become chemically protected against predators; they also use PAs as pheromone precursors.
