An Ocellar "Pupil" that Does Not Change with Light Intensity, but with the Insect Age in Triatoma infestans

The simple eyes (ocelli) of recently emerged adult Triatoma infestans exhibit a narrow elongated "pupil", surrounded by a ring of brown-reddish pigment, the "iris". This pupil does not respond to changes in the illumination, but varies in size after the imaginai ecdysis. This cha...
