A queen bumble bee (Bombus pratorum) climbing out of a Crocus tommasinianus flower. Bumble bees can only fly if their body temperature is above 30 degrees. Crocus flowers may help to keep the bee's temperature up. The petals have reverse papillate epidermal cells which are thought to help to focus the light,warming the petals and making the most of the heating ability of the light | |
