Flowers 
Some, like those London shops which are frequented by 
peers and peasants, satisfy every sort of insect, from the 
small fly to the hive-bee, There are small, cheap, 
economically-produced, white and yellow flowers (such 
as the crucifers) which do a small trade with ordinary 
flies, beetles and the like, and whose clients might be 
afraid of sucking honey beside bumble-bees and such- 
like pretentious personalities, just as the small “ general” 
shops of unfashionable London (that is, less valuable 
ground) are visited by poor customers. Then there are 
also large complex flowers, rich crimson, like red clover 
and Stachys silvatica, or with the deep blue of ajuga, 
purple of aconite, gold yellow of broom and whin, which 
only cater for insect-aristocrats. These flowers, like shops 
in Bond Street or Regent Street, are expensive to make 
and keep up, and would not be of any use to the general 
public. There are also many “specialists” which lay 
themselves out for one special and particular visitor. 
Figwort (Scrophularia) is a wasp-flower, and seldom used 
except by wasps, Veronicas, with little blue blossoms 
and two diverging stamens, are clearly intended for the 
small glancing hoverflies which visit them conscien- 
tiously, gathering the stamens under their legs and prob- 
ing the tube for honey. Even such a very odd-looking 
flower as the fumitory is specially intended for the 
cabbage white butterfly. 
Perhaps the most interesting of all are the white 
evening flowers_with long tubes and strong scent, such 
as evening campion and honeysuckle, which are fre- 
quented by evening moths. The moth has an evening 
habit, a long proboscis, and well-developed olfactory 
lobes. The flower opens at dusk only, has a long 
tube, and a strong fragrance which is only perceptible 
at night. 
These two, the evening campion and the moth, have
