The head of a recently emerged Green Grocer cicada,Cyclochila australasiae. Cicadas are members of the family Hemiptera. C. australasiae is widely distributed in coastal regions of Australia from South Australia to Southern Queensland. This picture,taken in Warrandyte Victoria in early December,is of an adult insect at rest on a garden table. It shows two compound eyes and three simple eyes (orange),known as ocelli. Compound eyes consist of many small individual units called ommatidia which produce a mosaic-like image. The function of ocelli is uncertain,but may be related to rapid perception of changes in light levels,assisting the insect to maintain stable flight | |
