Hairpencils, wing pouches and courtship of the butterfly Danaus chrysippus was studied in green houses. Before and after courtship, the males were observed to insert their abdominal hairpencils frequently into the wing pouches. Pheromones (Pyrrilizidinone) of the hairpencils are effective odour stimuli to the antennae (chemical communication: see also Hymenocera). | |
