Habits of Insects when visiting Flowers,” by Mr. R. M. 
The author records in detail the movements of 76 insects while 
engaged in visiting 2400 flowers. He tabulates the results, and 
concludes that insects do possess a decided preference for a number 
of successive visits to the same species of flowers, although this is 
not invariably the case. Most of the observations were made on 
bees, which seem to perform the fertilisation of at least one-half of 
all the flowers fertilised by insects in this country. Butterflies, as 
a rule, seem to wander purposelessly in their flight; nevertheless 
some species, including the Fritillaries, are fairly methodic. The 
author believes that it is not by colour alone that insects are guided 
from one flower to another of the same species, and the sense of 
distances, but good sight for short distances ; of 55 humble bees
