The mouthpieces of the butterflies are very specialized and modified in comparison to other insects. Their mandibles (upper jaw) are greatly stunted, only in the family of the Urmotten (Micropterigidae) these are still used as biting tools. In most of the butterflies, the mandibles (maxillae) form two flexible half-tubes, which are connected via seams. In this way, the suction tube is formed between the two tubes, with which the moths can absorb their food. This can only be liquid. Almost all butterflies feed on flower nectar, plant juices and other nutrient-rich liquids. The suction cup is placed under the head in a resting position. In addition to the altered maxillae, the butterflies have the Maxillarpalpen, which are reproduced, as well as labial phales, which are lengthened in many species (eg the subfamily Libytheinae the Edelfalter). On the palps, there are tactile and olfactory organs. Photo ©HomeArtPictures
