The light entering from the facet gets focused by the crystalline cone to the rhabdom. They can discern lights traveling on a horizontal plane, also known as polarized lights. In flies, these projections are fingerlike structures known as microvilli. Their butterfly brains collect all of that information and make one whole picture from all those tiny parts. In this blog I share all the tips and tricks that I know and I hope you’ll find it helpful. The Fly Summary. House fly eyes can recognize even the slightest movements in a wide field.

Flies have two compound eyes, one on each side of its head. A compound eye is a visual organ found in arthropods such as insects and crustaceans.It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.

Many little gnats and mosquitoes are crepuscular meaning they fly at dawn and at dusk but flies generally have eye modifications for frolicking around in the sunlight. The ommatidium is an energy transducer, i.e., the light stimulus absorbed by the rhabdom gets converted into electrical energy, which gets carried to the optic lobes of the brain by the optic nerves.
