Published: 01 December 2017
...Ajay Narendra; Willi A. Ribi ABSTRACT Insects have exquisitely adapted their compound eyes to suit the ambient light intensity in the different temporal niches they occupy. In addition to the compound eye, most flying insects have simple eyes known as ocelli, which assist in flight stabilisation...

...Yuri Ogawa; Willi Ribi; Jochen Zeil; Jan M. Hemmi 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 some insects have been shown to provide celestial...

...Richard P. Berry; William T. Wcislo; Eric J. Warrant SUMMARY Growing evidence indicates that insect ocelli are strongly adapted to meet the specific functional requirements in the environment in which that insect lives. We investigated how the ocelli of the nocturnal bee Megalopta genalis...

...Sebastian Schwarz; Laurence Albert; Antoine Wystrach; Ken Cheng Many animal species, including some social hymenoptera, use the visual system for navigation. Although the insect compound eyes have been well studied, less is known about the second visual system in some insects, the ocelli. Here we...

..., unlike the strictly diurnal A. cerana and A. florea , A. dorsata possess large ocelli, a feature that it shares with all dim-light bees. However, the eyes of the facultatively nocturnal A. dorsata are much less sensitive than those of known obligately nocturnal bees such as Megalopta genalis in Panama...

.... The fly can also sense rotation using its three ocelli (simple eyes), by comparing the light intensities measured at each ocellus. We report that an individually identified tangential cell, V1, responds in an apparently rotation-specific manner to stimulation of the ocelli. This effect was seen...

... the responses recorded in their axons or terminal regions. INTRODUCTION The cockroach has two ocelli and each ocellus contains about 10000 photoreceptor cells, which converge on four large, second-order neurones (L-neurones) (Weber & Renner, 1976). There are apparently no differences among the four L-neurones...
