Abstract

Adults of Astylus rubricostatus deferid inflorescences of the herb Gaillardia megapotamica var radiata
(Griseb) Baker against intrusión by conspecific individuáis. It is probable that the behaviour is a result from
competition among individuáis of both sexes for the amount of polen contained by flowers of G. megapotamica, which seems to be the limiting resource.
