Butterfly proboscis. Light micrograph of the coiled proboscis ('tongue') of a butterfly. The proboscis of a butterfly consists of two half-tubes which join together in the mid-line to form a single tube for sucking up fluids,mainly nectar from flowers. The tube is reinforced by sclerotised rings. At the end of the tongue are sensory spines (papillae). This image has been enhanced to show up the rings (green),the joining of the two half-tubes (brown),and the sensory papillae (yellow). Magnification: x103 when printed at 10 centimetres across | |
