Come, Meet Papilio Demoleus Caterpillar "Luckily again, I also had accidentally encountered when the butterfly was trying to get out of its fragile cocoon" Hi guys! Do you guys plant an orange tree around the yard? If yes is certainly no stranger to this petite animal. Is a child or larva of Papilio Demoleus butterfly or often called Lime Butterfly or orange butterfly. These butterflies are so common we find flying between the flowers both in the yard, the park and the clearing of the clearing. By experts, this type of butterfly is inserted into the "swallowtail butterfly" class even though it does not have a sword-like bulge on its hind wings.
