Summary1.Examination of the marginal region of the compound eyes of orthorrhaphan Brachycera and Cyclorrhapha (Diptera) revealed special ommatidia with unusually thick central columns from rhabdomeres. (The cross-sectional area of the column is 1.3-17 times the normal size according to species; morphometric data on this and points 4–7 are given in Table 1.) These special ommatidia existed in all our 29 species from 13 families (4 from orthorrhaphan Brachycera, 9 from Cyclorrhapha).2.The… Expand
Morphologische Indizien für das unmittelbare Schwestergruppenverhältnis der Schizophora mit den Syrphoidea (‘Aschiza’) in der phylogenetischen Systematik der Cyclorrhapha (Diptera: Brachycera)
TLDR
The retinal pair was accorded a high relevance as an indicator of the phylogenetic relationships in Cyclorrhapha owing to its special morphology and the very low probability of a parallel development of the apomorphous monotype. Expand
THE EYE OF THE TENEBRIONID LEPISPILUS SULCICOLLIS ( COLEOPTERA ) AND SOME ECOPHYSIOLOGICAL PREDICTIONS BASED ON EYE ANATOMY

Regional differences in a nematoceran retina (Insecta, Diptera)
TLDR
These findings, together with observations of behavior, imply that the psychodids have well-developed visual abilities, as the eye can adapt by a number of retinomotor processes. Expand
Optic lobe projections of marginal ommatidia in Calliphora erythrocephala specialized for detecting polarized light
TLDR
These neuronal arrangements suggest two novel features of the insect optic lobes and brain that imply that each lobe receives a common input from areas of the left and right eye, specialized for detecting the pattern of polarized light. Expand
Crustacean-like rhabdoms at the dorsal rim of several dipteran eyes (Syrphidae, Tabanidae)

Raman-atomic force microscopy of the ommatidial surfaces of Dipteran compound eyes.
TLDR
It is demonstrated that the atomic force microscope (AFM) is a potentially useful instrument for gathering phylogenetic data and that the newly developed Raman-AFM may extend this application by revealing nanometer-scale surface chemistry. Expand
Properties of photoreceptors R7 and R8 in dorsal marginal ommatidia in the compound eyes ofMusca andCalliphora

TLDR
Intracellular recordings were made from R7 and R8 photoreceptors in dorsal marginal ommatidia in the flies Calliphora erythrocephala andMusca domestica identifying the cells as the specialised marginal photoreceptor described by Wada (1974b) and showing that they project long visual fibres to the medulla. Expand
The bright zone, a specialized dorsal eye region in the male blowflyChrysomyia megacephala
TLDR
This eye provides a clear example of an insect where large dorsal facets have evolved not for higher acuity, but rather for higher light capture, and it is suggested that the combination of high photon capture and rounded angular sensitivities is advantageous for monitoring movement and position of small objects. Expand
Compound eyes of insects and crustaceans: Some examples that show there is still a lot of work left to be done
TLDR
Research on the embryology and molecular control of the development of the insect clear‐zone eye with superposition optics is one of the suggestions, because almost all of the developmental work on insect eyes in the past has focused on eyes with apposition optics. Expand

Ein spezieller Rhabdomerentyp im Fliegenauge
TLDR
At least in the Tabanidae, Rhagionidae, and Syrphidae, this rhabdomere complex is composed of the interdigitating segments of the rhabDomere 7 and 8. Expand
The rhabdomeric microvilli of several arthropod compound eyes kept in darkness
TLDR
The rhabdomeric microvilli of the individuals kept in darkness for a long period were regularly arranged as in normal eyes in the material prepared by double fixation with glutaraldehyde andOsO4, whereas in those fixed solely by OsO4 various forms of vesiculations were seen. Expand

SummaryIn the ommatidia of Musca, the light flux transmitted by each one of the rhabdomeres of sense cells no. 1 to 6 decreases as a function of time if light falls onto these rhabdomeres. With aExpand
The fine structure of the central cells in the ommatidia of dipterans.
TLDR
The anatomical arrangement of the superior and inferior central cells, together with the independence of their axonal pathways, suggests that they may represent an intraommatidial polarized light analyzer. Expand
Some aspects of the retinal organization of Sympycnus linetaus Loew (Diptera, Dolichopodidae).
TLDR
The results imply that the corneal interference filters causing the facet colors have neurological representations in the visual centers and therefore can serve a visual function, possibly as the first elements of a color contrast enhancement system. Expand

Comparative ultrastructure of corneal surface topography in insects with aspects on phylogenesis and function
TLDR
The higher relative number of group II and III corneas (low- and full-sized nipples) in the anagenetieally highest orders and the exclusive occurrence of group III corNEas in the most advanced orders, Trichoptera and Lepidoptera, may indicate a progressive development of nipples during phylogenesis.
