FORM PERCEPTION IN PAPILIO DEMOLEUS L. (PAPILIONIDAE, LEPIDOPTERA) by VIDYADHAR G. VAIDYA 1) (Department of Zoology, University of Poona, India) (With 3 Figures) (Rec. 6-VII-1968) INTRODUCTION By perception of form is meant the perception of the geometrical qualities of an object, as for example, surface area and the degree of contour. In nature the qualities of colour and form are mixed up in flowers. As already pointed out by KUGLER (1952), the relations between flower colour and flower form with respect to insect vision are very complex, and therefore, a clear understanding of the relations between a particular insect and flower colour alone or flower form alone is not possible. The present series of experiments were therefore so designed as to bring out the interrelationship between colour perception and form perception by Papilio demoleus. The behaviour of insects towards different forms has been under investi- gation for many years. The pioneer work in Lepidoptera is that of ILSE ( r932 ) with certain Vanessidae. Therefore from the point of view of com- parative physiology also, it was of great interest to study the form discrimina- tion and form preference of a Papilionid, about which nothing was yet known.
