Catchment areas of panoramic snapshots in outdoor scenes.
The results show that view-based homing with panoramic images is in principle feasible in natural environments and does not require the identification of individual landmarks.

A detailed film analysis shows that orientation flights in solitary wasps of the genus Cerceris consist of a systematic behavioural sequence: after lift-off from the nest entrance, wasps fly in ever increasing arcs around the nest.
The information content of panoramic images I: The rotational errors and the similarity of views in rectangular experimental arenas.
It is shown that the relative salience of different visual cues determines whether image differences are dominated by geometry or by features, which is implicitly contained in panoramic images and does not require explicit computation by a dedicated module.
Fundamental differences in the optical structure of the eyes of nocturnal and diurnal mosquitoes
The anatomy and optics of the eyes of a range of mosquito species from the wholly dark-active blood-feeding Anopheles gambiae to the diurnal plant-feeder Toxorhynchites brevipalpis are studied, finding that dark- active and crepuscular species have short fused rhabdoms with a conical construction.
Robber bees (Lestrimelitta limao) and their host chemical and visual cues in nest defense byTrigona (Tetragonisca) angustula (Apidae: Meliponinae)
It is concluded that guard bees recognize L. limao by the major terpenoids of their volatile cephalic secretions, geranial, neral (=citral) and 6-methyl-5-hepten-2-one; other components may fine-tune this recognition.
The visual ecology of fiddler crabs
How deeply embedded fiddler crab vision is in the behavioural and the physical ecology of these animals and, on the other hand, how their behavioural options are constrained by their perceptual limitations are shown.
Eyes, eye stalks and the visual world of semi-terrestrial crabs
It is shown that elongated eye stalks and acute zones for vertical resolving power are specific adaptations to the problems of spatial vision in a flat environment and could enable animals to gain depth and size information monocularily from retinal position and retinal size alone.
Visually mediated species and neighbour recognition in fiddler crabs (Uca mjoebergi and Uca capricornis)
This work demonstrates the use of claw coloration as a species recognition signal in a fiddler crab and shows that distinct carapace colour patterns in Uca capricornis enable males to discriminate between their female neighbours and unfamiliar females.
Structure and function of learning flights in bees and wasps
The consequences of the structure of learning flights for visual information processing are reviewed and how they may relate to the acquisition of a visual representation and the task of pinpointing the goal are discussed.
