This table is of course only a very rough approximation, 
but it serves to show, approximately, the relative numbers of 
visits received by the different flowers, or paid by the differ- 
ent groups of insects. It brings out, even better than the 
preceding tables, the enormous preponderance in Britain of 
short-tongued flies. Even in Scabiosa , the flower of highest 
type in the above list, they form a large proportion of the 
total visitors. We must remember also that the efficacy in 
cross-fertilization of a group of insects depends, for any 
locality, much more on the number of individuals visiting 
than on the number of species. 
The list is also of interest as showing the choices made by 
the various insect groups in an extremely limited flora (note 
e. g. the bees).
