The term "ocellus" (plural ocelli) is derived from the Latin oculus (eye), and literally means "little eye". In insects, two distinct ocellus types exist: [9] dorsal (top-most) ocelli, and lateral ocelli (often referred to as ocelli and stemmata, respectively), most insects have dorsal ocelli while stemmata are found in the larvae of some ...
The body also contains parenchymatous tissue that explains the free movement of the locomotory waves the species utilizes. [10] The species' ventral and dorsal body walls can range from 35-40 microns in thickness. [7] The body wall of Notoplana acticola is considered bilaterally symmetrical that assist in the formation of tissue. [10]
The scape and pedicel generally comprise a single segment each. The antennal formula is used to describe the number of segments in each of the components of the antenna (scape; pedicel; anelli, funicle; clava). An antennal formula of 1:1:2:4:3 indicates an antenna with a scape, a pedicel, 2 anelli, 4 funicular segments, and 3 segments in the ...
[11] [21] The ocelli are not homologous to the simple eyes of caterpillars which are differently named as stemmata. [5] The ocelli of Lepidoptera are reduced externally in some families; where present, they are unfocussed, unlike stemmata of larvae which are fully focussed. The utility of ocelli is not understood at present. [5]
2. Anchovies. While eaten on pizzas, in Caesar salad, or on toast, anchovies only became part of the American diet when Italian immigrants started adding them to restaurant menus. While they're a ...
Some reptiles, such as the sand lizard of Europe, have eyespots; in the sand lizard's case, there is a row of spots along the back, and a row on each side. [12]Many species of cat, including Geoffroy's cats, jungle cats, pampas cats, and servals, have white markings, whether spots or bars, on the backs of their ears; it is possible that these signal "follow me" to the young of the species.
Fore wing with from two to four, hind wing normally with seven ocelli, similar to, but more clearly defined than, the ocelli on the upperside ; on both wings the line of ocelli bordered inwardly and outwardly by sinuous purplish-white lines. On the hind wing only the three posterior ocelli in a straight line, the rest strongly curved outwards.
