In autumn, caterpillars of the Oleander Butterfly visit my potted Weeping Fig. The Oleander Butterfly has a wing span of 7.5 cm and is very dark brown or black, with white blotches on both wings and body. The caterpillars arrive in an amusing little caravan formation, travelling head to tail, then spent about a week munching on the fig foliage before each forms a chrysalis. I don’t know where they breed because we don’t have any Oleanders, but they seem to enjoy leaves from plants that have milky sap. I leave these creatures in peace because they do little damage to the tree, and the chrysalises are so pretty.
