Anthecological observations on an orchid Cremastra appendiculata var. variabilis were carried out during May and June, 1994, in Kobe, Japan. The pendulous, tube‐shaped flowers were visited by three species of bees and two of syrphid flies. Only queens of a long‐tongued bumble bee Bombus diversus diversus received the pollinarium on one of their fore‐femora. The frequencies of Bombus flower visits were extremely low. A carpenter bee, Xylocopa appendiculata circumvolans , consistently robbed nectar by making a perforation at the flower base.
