COMPOUND EYES of a STRIPED HORSE FLY (Tabanus lineola), Female, with thousands of individual lenses constructed for seeing images--this is a highly efficient eye. Some insects have simple eyes, but most adults have compound eyes. Males nourish themselves with nectar, however, the females bite and produce blood flow with knifelike mouthparts and they have a spongelike proboscis to ingest the blood. Some of the mouthparts and antennae are discernible. The forelegs adapted for grasping are also seen. Common in the eastern United States. Michigan
