Abstract
In adult blow flies (Calliphora vicina), unilateral or bilateral cuts between the optic lobes and the brain, or complete bilateral lobectomy , failed to interrupt the circadian rhythm of locomotor activity or it s entrainment to a daily light:dark cycle. It is concluded that the re levant circadian pacemakers are not within the optic lobes and that th e compound eyes are not the photoreceptors for entrainment. As in othe r holometabolous insects, the pacemakers (the ''clock'') and the photo receptors may lie in the brain.
