The space between the two eyes can sometimes be reduced to a narrow strip running from the front of the occipital region, or disappear altogether because of the direct contact between the eyes or their margins. The morphology of the compound eye is characterized by a significant number of ommatidia, of the order of thousands in muscoids. The ...
Head of a horse-fly showing large compound eyes and stout piercing mouthparts A head of a fly, showing the two compound eyes and three simple eyes clearly. Flies have a mobile head with a pair of large compound eyes on the sides of the head, and in most species, three small ocelli on the top. The compound eyes may be close together or widely ...
In flies such as the mosquitoes, that have long antennae, the labella are two separate organs, attached to the proboscis only at their bases, but in the flies with short antennae, such as the house fly, they are more or less fused to form a single structure. Flies with fused labella have food channels in the surface of the labella.
An image of a house fly compound eye surface by using scanning electron microscope Anatomy of the compound eye of an insect Arthropods such as this blue bottle fly have compound eyes. A compound eye may consist of thousands of individual photoreceptor units or ommatidia (ommatidium, singular). The image perceived is a combination of inputs from ...
Compound eye of a house centipede Compound eye of a dragonfly. A compound eye is a visual organ found in arthropods such as insects and crustaceans.It may consist of thousands of ommatidia, [1] which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.
Early schizochroal eye designs appear haphazard and irregular – possibly constrained by the geometrical complications of packing identical sized lenses on a curved surface. Later schizochroal eyes had size graduated lens. [22] The abathochroal eye is the third eye morphology of trilobites, but it has found only within the Eodiscina. This form ...
The lesser house fly (Fannia canicularis) , commonly known as little house fly, is a species of fly. It is somewhat smaller (3.5–6 mm (0.14–0.24 in)) than the common housefly and is best known for its habit of entering buildings and flying in jagged patterns in the middle of a room. It is slender, and the median vein in the wing is straight.
