Résumé :

Abdominal scopas (pollen collecting brushes) of 92 species of Megachilid bees have been studied with the Stereoscan. The scopal setae of different species could be classified into six different types, although transitions do exist from one type to another. In most species all setae from the same scopa are alike, but in some species different types coexist in the same scopa, arranged into a gradient showing transitions from one type to another. Those facts allow us to conclude at the existence of a scopal field by the transformation of both non-specialized setae hitherto described. Suggestions are presented to explain the specific diversity of scopal setae. © 1974.
