The spiders of New Zealand
The spectral sensitivities of identified receptors and the function of retinal tiering in the principal eyes of a jumping spider
Summary1.The functional organisation of the central retina of the anterior median (AM) eyes of a jumping spider,Plexippus (Salticidae) is examined by anatomical, electrophysiological and opticalExpand
The Function of Eyespot Patterns in the Lepidoptera
It has been shown that many small passerines possess inborn responses to their predators, and it is probable that these are "parasitised" by the eyespot patterns of insects. Expand
Comparative ultrastructure of Layer I receptor mosaics in principal eyes of jumping spiders: the evolution of regular arrays of light guides
The present material confirms that the evolution of retinal tiering preceded that of a foveal Layer I mosaic of high acuity in the Lyssomaninae as well as Spartaeinae and that the evolutionary history of Layer I in the Salticinae remains obscure. Expand
The optic lobes of Lepidoptera.
Variants of the Golgi-Colonnier (1964) selective silver procedure have been used to show up neurons in insect brains. Neural elements are particularly clearly impregnated in the optic lobes. ThreeExpand

The posterior median eyes of Dinopis subrufus are probably the largest simple eyes found in arthropods, and it is shown that spherical aberration has been overcome. Expand
The generation of ultrasonic signals by a New World arctiid moth
The sounds generated by the metathoracic tymbal organs of the arctiid moth Meles laodamia Druce are described and related to their structure. Each tymbal is a swollen air-filled katepisternalExpand
The sensitivity of receptors in the posterior median eye of the nocturnal spider,Dinopis
Intracellular and extracellular (ERG) recordings were made of receptor responses in the posterior median eye of the nocturnal spider Dinopis subrufus, which indicates a retina dominated by photoreceptors containing a single 517 nm rhodopsin. Expand
The tracheal arrangement and the classification of linyphiid spiders
The tracheal arrangement of 121 species of European Linyphiidae has been examined and it is found that Allomengea is anomalous in that the medial tracheae are extensively branched but remain confined to the abdomen. Expand
Built-in polarizers form part of a compass organ in spiders
Behavioural experiments show that the spiders are primarily active after sunset and that they use polarization cues to find their way back to the nest after foraging trips, and measurements using a model eye indicate that the compass organ is best suited for navigation at dusk and dawn. Expand
