Coexpression of three middle wavelength-absorbing visual pigments in sexually dimorphic photoreceptors of the butterfly Colias erate
The tiered ommatidia of the Eastern Pale Clouded yellow butterfly, Colias erate, contain nine photoreceptor cells, four of which contribute their rhabdomeral microvilli to the distal tier of theExpand

Sex-specific retinal pigmentation results in sexually dimorphic long-wavelength-sensitive photoreceptors in the eastern pale clouded yellow butterfly, Colias erate
SUMMARY The compound eyes of the eastern pale clouded yellow butterfly, Colias erate, contain three types of ommatidia (I, II and III), identifiable by the differing arrangements of pigment clustersExpand

Three spectrally distinct photoreceptors in diurnal and nocturnal Australian ants
Ants are thought to be special among Hymenopterans in having only dichromatic colour vision based on two spectrally distinct photoreceptors. Many ants are highly visual animals, however, and useExpand

Moving in Dim Light: Behavioral and Visual Adaptations in Nocturnal Ants.
Visual navigation is a benchmark information processing task that can be used to identify the consequence of being active in dim-light environments. Visual navigational information that animals useExpand

Regional differences in the preferred e-vector orientation of honeybee ocellar photoreceptors
ABSTRACT In addition to compound eyes, honeybees (Apis mellifera) possess three single-lens eyes called ocelli located on the top of the head. Ocelli are involved in head-attitude control and in someExpand

Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights
Queens of social insects make all mate-choice decisions on a single day, except in honeybees whose queens can conduct mating flights for several days even when already inseminated by a number ofExpand

A new method for mapping spatial resolution in compound eyes suggests two visual streaks in fiddler crabs
We present a new method for estimating the spatial and optical resolution of compound eyes, using the 3D micro-CT images of preserved animals. Expand

Spatial Resolving Power and Contrast Sensitivity Are Adapted for Ambient Light Conditions in Australian Myrmecia Ants
The eyes of most animals exhibit a trade-off between spatial resolving power and absolute sensitivity, which likely reflects functional adaptations for the animals’ visual ecology. When animalsExpand

Miniaturisation reduces contrast sensitivity and spatial resolving power in ants
ABSTRACT Vision is crucial for animals to find prey, locate conspecifics and navigate within cluttered landscapes. Animals need to discriminate objects against a visually noisy background. However,Expand

Calling and Courtship Behaviors Initiated by Male-Male Contact Via Agonistic Encounters in the Cricket Gryllus bimaculatus
We investigated the stridulatory courtship initiated by male-male contact after agonistic encounters and the effect of dominance status on subsequent reproductive behavior in the cricket GryllusExpand
