Butterflies and moths (Lepidoptera) represent the second most diverse taxa of animals with approximately 160, 000 named species. Lepidoptera feed on various liquids (e.g., nectar, sap, rotting fruit, blood) using specialized mouthparts (proboscis) that function as a conduit for transporting fluids from pools and wetted surfaces to the insects gut. Most previous reports assume (via gross morphology) that the proboscis functions as a drinking straw; fluid rise is coupled with sucking pump action and requires minor capillary influence. Recent research, however, has provided evidence that the proboscis incorporates capillarity and wettability dynamics for fluid rise. In addition, butterflies with partially split mouthparts were recently demonstrated to retain their feeding ability. The purpose of this project is to study fluid rise abilities in proboscises where the sucking pump has been disabled and to determine if butterflies can feed with completely split proboscises. Capillary action, wettability, and structural architecture play a more important role in fluid rise abilities in split proboscises (C-shaped conduit) than the sucking pump. Butterflies were also shown to retain their ability to feed with completely split proboscises, however, the sucking pump may be important for transporting fluids down the alimentary canal. The ability for fluids to travel against gravity in C-shaped conduits has application to the field of microfluidics for the production of microfluidic devices.
