Venustaconcha are small lampsilines that are typically found in headwater streams and that  utilize darters and sculpins as hosts.  The lure of Venustaconcha pleasii consists of a small mantle flap fringed with papillae.  The flaps periodically flip closed and open, revealing the marsupial gills within.  This movement is very responsive to disturbances such as shadows and vibration.
