HUMBLE BEE (Bombus terrestris, B. lucorum, Sc.). 
Humble Bees (see Fig. 245) have been known to damage 
Beans and cultivated flowers that have the nectar at the 
bottom of a long tube, by boring a hole in the calyx to 
obtain the nectar more easily. The flowers are not 
fertilised when robbed in this way, and the seeds become

abortive. Yet though this at times oceurs, the damage 
done by it is so slight that the Bees ought to be regarded 
as useful allies, because of the services rendered by them 
in conveying pollen from flower to flower. There is reason 
to believe that certain plants, e.g., Red Clover, are depen- 
dent on Humble Bees for their fertilisation. Should the
