The maxilla) when opposed form a tube like the proboscis of a butterfly, which is, however, not capable of being rolled up. Why do insects go to flowers and Reasons for Attractlou. „,, , .,, ,, 01 what advantage is it to the plant? Insects go to the flower because it offers food, nec- tar, pollen, or other substance. The insect must care and provide for its young. Plants would not long provide this food without some advantage accruing to them, hence we have reciprocal adaptations. Note as an illustration the adaptation in sage, clover, etc., or in certain nocturnal Lcp- idoptera that lay their eggs in the flowers of some pinks, as Soapwort. The larvae after hatching, feed on the young ovules and seeds. When mature they bite a hole through the aide wall of the ovary and escape. These insects do not.
