Willis and BurkilL — Flowers and 
The Clova visitors to this species are a little more specialized 
than those to Leontodon autumn ale, the cause being in its 
earlier flowering. Andrena showed some measure of constancy, 
as also did Eristalis. The young flowers close at night and 
remain closed by day during rain. Mid-tongued bees are the 
most numerous in the list of North Central Europe and mid- 
tongued flies stand second.
