Adult males of the insect order Strepsiptera are characterized by an unusual visual system that may use design principles from compound as well as simple eyes. The lenses of this eye are unusually large and focus images onto extended retinae. The light-gathering ability of the lens is sufficient to resolve multiple points of an image in each optical unit. We regard each unit as an independent image-forming eye that contributes an inverted partial image. Each partial image is re-inverted by… 
Behavioral evidence for within-eyelet resolution in twisted-winged insects (Strepsiptera)
TLDR
This study is the first to use the EMD model explicitly to investigate the possibility that strepsipteran eyes combine motion detection features from both camera and compound eyes.
The visual system of male scale insects
Animal eyes generally fall into two categories: (1) their photoreceptive array is convex, as is typical for camera eyes, including the human eye, or (2) their photoreceptive array is concave, as is
Stark trade-offs and elegant solutions in arthropod visual systems
TLDR
This Review summarizes exciting solutions that animals have evolved in response to specific visual challenges in arthropods, and they are best understood in light of the physical limitations of vision.
Photoreceptor projections and receptive fields in the dorsal rim area and main retina of the locust eye
TLDR
The projections of photoreceptors and their receptive fields in the main eye and dorsal rim area of the desert locust, a model system for polarization vision analysis, are studied to challenge previous reports and provide data for future analysis of peripheral networks underlying polarization opponency in the locust brain.
Mineral eyes : lessons from the natural world
The compound eyes of trilobites, which appeared in the Early Cambrian, represent one of the first preserved visual systems. Application of state-of-the-art microscopy techniques in the present study
The Dynamic Evolutionary History of Pancrustacean Eyes and Opsins.
TLDR
The evolutionary history of eyes and opsins across the principle groups of Pancrustacea is examined, revealing a particularly dynamic history, with losses of eyes, duplication and loss of opsin genes, and changes in opsin expression between types of eyes.
The unusual eyes of Xenos peckii (Strepsiptera: Xenidae) have green- and UV-sensitive photoreceptors
TLDR
Electroretinogram-based spectral response measurements suggest dichromacy in twisted-wing parasites, and raise the possibility that UV vision plays an important role in the ability of X. peckii males to find the very cryptic strepsipteran females that are situated within their wasp hosts.

TLDR
The optic lobes of Diptera have been examined by variants of the Golgi-Colonnier selective staining techniques and by reduced silver procedures and some lateral relationships have been reconstructed between elements in regions whose columnar arrangement is clearly discernible in Golgi preparations.
The functional organisation of locust ocelli
TLDR
It is suggested that the disposition of locust ocelli, the spectral sensitivity and the temporal and spatial filtering characteristics of their L neurons suit these cells well to the task of detecting instability in flight.
Trilobite vision: a comparison of schizochroal and holochroal eyes with the compound eyes of modern arthropods
TLDR
Analysis of trilobite vision is strengthened by the use of new mathematical approaches to compound eye design, which implies that function of the holochroal eye was similar to that of modern arthropods, and that they were used in moderate to dim intensities of light.
Functional Neuroanatomy of the Blowfly’s Visual System
TLDR
Outputs from the optic lobes arise mainly in the lobula (Lo) and lobula plate (LP), two neuropils each with distinct architectures, which are thought to be involved in visual stabilization of flight.
Anisotropic imaging in the dragonfly median ocellus: a matched filter for horizon detection
Abstract. It is suggested that the dragonfly median ocellus is specifically adapted to detect horizontally extended features rather than merely changes in overall intensity. Evidence is presented
Optical properties of the ocelli of Calliphora erythrocephala and their role in the dorsal light response
TLDR
The results show that, in Calliphora, the ocelli have little influence on head orientation during flight, and must be assumed to serve other functions.
The optomotor response and spatial resolution of the visual system in male Xenos vesparum (Strepsiptera).
TLDR
The behavioural data strongly suggest that, at least for the optomotor response, the resolution of the strepsipteran compound eye is limited by the ommatidial sampling array and not by the array of retinula cells within each o mmatidium.
Chunk versus point sampling: visual imaging in a small insect.
TLDR
Anatomical and optical measurements indicate that each of these units is image-forming, so that the visual field is subdivided into and represented by "chunks," unlike the conventional insect compound eye that decomposes the visual image in a pointwise manner.
Structure of the visual system of the larva of the tiger beetle (Cicindela chinensis)
TLDR
The visual system of the larval tiger beetle (Cicindela chinensis) consists of six (two large, two mediumsized, and two small) stemmata on either side of the head, and an underlying neuropil mass which contains a single giant monopolar neuron.
Optical and physiological properties of the larval visual system of the tiger beetle, Cicindela chinensis
TLDR
The larva of the tiger beetle possesses six stemmata on either side of the head that possessed a single type of retinular cell with a maximal spectral sensitivity at 525 nm, and a flicker fusion frequency of 25–50 Hz.
