Résumé :

The hairs covering the legs of several species of female megachilid bees are arranged in imbricated fields. At the boundaries of these fields, either the hairs show a morphology intermediate between those of the contiguous fields, or there is a narrow strip with an irregular mosaïc of several hair types. It is suggested that: 1. The structure of the hairs may be determined by the territory in which the trichogenous cell is located. 2. Some morphogenetic fields are bidimensional and cross the segmentary boundaries. The name ‘regional fields’ is proposed for them. 3. The regional fields may be modulated within each segment into which they extend. © 1973, Longman Group Ltd.. All rights reserved.
