Morphological colour change (2): The effects of total and partial blinding on epidermal ommochrome content in the stick insect,Carausius morosus Br.

Abstract

Fourth instar larvae of the stick insect,Carausius morosus, kept at 20°C in 16:8 LD, contained about 10 μg/animal of epidermal ommochrome. Surgical removal of the ventral half of each eye caused an increase to 110 μg/animal. A similar response (90 μg/animal) is produced by masking the ventral eye-halves with black varnish. Masking or surgically removing the… (More)
