This Chocolate Pansy, featured today belongs to the same family as the Bushbrown's featured below- Nymphalidae. I spotted this butterfly, while walking among a patch of overgrown weeds in our backyard.
Tracking of mates in both butterflies and moths occurs by the release of sex pheromones by the females from glands located on their abdomen. The antennae of the males have sensory papillae, which guide the males to their mates. These pheromones are a cocktail of chemicals and in some butterflies a pheromone released by the males make the female more receptive and ready to mate.
