Abstract
The occurrence of enlarged ocelli in nocturnal foraging bees has led to a quantitative study of the relation between ocellar size and foraging activity in a number of species of bees. The results show a negative correlation between ocellar size and the light intensity threshold of foraging. Ocelli also increase with head size, but this relationship is not as good a predictor of ocellar size as is the light intensity threshold. The results were all compatible with the observation that ocelli serve as enhancers of the sensitivity of the compound eyes.This publication has 0 references indexed in Scilit:
