...Manuel Rocha; Kyle J. Kimler; Matthew T. Leming; Xiaobang Hu; Michelle A. Whaley; Joseph E. O'Tousa ABSTRACT During the larval stages, the visual system of the mosquito Aedes aegypti contains five stemmata, often referred to as larval ocelli, positioned laterally on each side of the larval head...

...Elke K. Buschbeck Stemmata, the eyes of holometabolous insect larvae, have gained little attention, even though they exhibit remarkably different optical solutions, ranging from compound eyes with upright images, to sophisticated single-chamber eyes with inverted images. Such optical differences...

... of these animals. This is because these eyes have enhanced focal lengths (~400–600 μm) compared with other insect eyes [e.g. the focal length of the enlarged stemmata of the predatory tiger beetle larvae is ~200 μm ( Mizutani and Toh, 1995 )]. Generally, twice the focal length results in twice the image...

...Srdjan Maksimovic; Tiffany A. Cook; Elke K. Buschbeck SUMMARY Larvae of the sunburst diving beetle, Thermonectus marmoratus , have a cluster of six stemmata (E1-6) and one eye patch on each side of the head. Each eye has two retinas: a distal retina that is closer to the lens, and a proximal retina...

...Toshio Ichikawa ABSTRACT Spatial and chromatic properties of 25 types of medulla neurones which integrate input from different optical units (stemmata) of the larval eye in the swallowtail butterfly were examined by illuminating individual stemmata with chromatic stimuli. Eleven neurones received...
