	Rosenzweig CHAPTER 5
		Each of these ocelli is situated on a separate plane, with the 3 planes forming a 90 0 angle with one another and thus panoramically encircling the dome at the tip of the vertex.
		The domeshaped corneas of the ocelli protrude outwards at an orientation of 90 0 to one another, with the distance between the two lateral ocelli being 330 µm while that between them and the median ocellus is 250 µm (Plate I, Figure B).
		The lens of the ocelli is homologous to the comus of the ommatidium.

	Rosenzweig SUMMARY
		The macroscopic structure of the ocelli and their spatial orientation enable the hornet, on the one hand, to determine the sun's direction during flight, and on the other hand they serve as a clock that lends hornets a temporal orientation.
		Three ocelli are situated in the vertex plate which is shaped like a three-sided pyramid with a truncated tip.
		As for the paraocellar crests, these actually function as gyroscopes and consist of a fluidfilled canal encased by a ciliary cells, the whole of which is rather analogous to the semicircular canal in the ear of vertebrates.

		Ocelli are light-sensitive regions in single-celled organisms or light-sensitive cells in animals.
		These ocelli contain two different types of pigmented cells: some that shade and some that are light-sensitve.
		This type of ocellus allows an animal to not only perceive the direction of a light source, but also, because of its multicellular nature, to detect an object moving past it—the shadow is detected by one cell after another as it moves across the ocellus.

		Then they beamed a pattern of flickering light on the fly's ocelli, similar to what it would see if it was rotating in the air.
		Ocelli contain a single lens, and generate blurry images, as if looking at the world through a piece of tissue paper, Parsons explained.
		But ocelli are much quicker at jetting signals to the fly's brain—a characteristic important when a fly is poised to possibly crash.

	Eyes
		The length of the ocelli (from front to rear, called ocellar length), the distance between them (called inter-ocellar distance), the shape of the ocelli, and the distance from each ocellus to the compound eye on the same side of the head (called ocellar-ocular length), differentiate the three Gryllotalpa remaining species as follows:
		In the European mole cricket the ocelli are nearly circular, and the the ocellar-ocular distance is greater than the ocellar length.
		In the knife and oriental mole crickets, the ocelli are elliptical, and the ocellar-ocular distance is less than the ocellar length.

		Ocelli are very important to airborne insects, using UV and green light to maintain straight and level flight.
		Research has shown that dragonflies are far more reliant on their ocelli than other flying insects, partly because of their unique ability to create a focussed image rather than just shades of light.
		The ocelli project grew from experiments first conducted at ANU in the 1970s and the current work on using vision for flight control began with funding from DSTO and the USAF in 1996.

	Insect Morphology and Anatomy (The Head)
		The 'frons' = that area of the face below the top two 'ocelli' and above the 'frontoclypeal sulcus' (if and when this is visible) and in between the two 'frontogenal sulci', it supports the 'pharyngeal dilator' muscles and in immature forms it bears the lower two arms of the ecdysial cleavage lines.
		The retinula cells are connected to axons at the base of the eye, it is these which carry the information collected by the lenses and converted into electrical impulses by the rhabdom to the brain, thus allowing the insect to see.
		Ocelli are present in most insects to some degree, though as with all aspects of insect anatomy there is a great deal of variety in form and even in relative function.

		In all species the ocelli on the wings and tail are either circular or oval, and consist of a beautiful, iridescent, greenish-blue or greenish-purple disc, with a fl border.
		malaccense, the ocelli on the tail-coverts are, as we have seen, confluent; and these feathers are of unusual length, being two-thirds of the length of the tail-feathers, so that in both these respects they approach the tail-coverts of the peacock.
		But even in the most perfect ball-and-socket ocelli a slight difference in the tints, though not in the shading, between the upper and lower parts of the ball can be perceived, as before noticed; and the line of separation is oblique, in the same direction as the bright coloured shades of the elliptic ornaments.

		The Southeast Asian pheasant genus Polyplectron is comprised of six or seven species which are characterized by ocelli (ornamental eye-spots) in all but one species, though the size and distribution of ocelli vary among species.
		The two least ornamented Polyplectron species, one of which completely lacks ocelli, have been considered to be the primitive members of the genus, implying that ocelli are a derived trait.
		Maximum likelihood and maximum parsimony analyses of cytochrome b sequences suggest that the closest relatives of Polyplectron are probably the peafowl and the argus pheasants.

		Ocelli: Simple eyes on some adult and larval insects.
		Typically there are three, which form an inverted triangle dorsally, the function of which is obscure.
		Some of the simplest eyes, called ocelli, can be found in animals like snails, who cannot actually "see" in the common sense.

	Ocelli
		Nonetheless ocelli -- eyespots on the wings of butterflies and moths -- exemplify the work of fiction in an ecology of predators.
		Rather than crises of representation, such markings produce movement and flight; they are an aspect of the Umwelt of organisms, as much an element of their locomotion and fitness as wings themselves -- they are techniques of flight that require no movement; movement is provoked in the other.
		Instead, Dick’s ocelli, in their hallucinogenic provocations, enable the breakdown of our space/time matrices of linear time, an allopoetic breakdown that, for Dick, more fully prepares us for the actuality of a dislocating alliance.

		Left and right ocelli are derived from the left and right eye-antennal imaginal discs, while the median ocellus derives equally from both discs once they fuse together after puparium formation.
		The axons from four separate transient populations of about 50 ocellar pioneer neurons (one from each lateral ocelli, and one each from right and left rudiments of the median ocellus) project from the pupal ocelli to the brain.
		At a later pupal stage, the adult ocellar photoreceptors are born and differentiate concentrically outside the cluster of pioneers.
