Two lateral ocelli are directed to the left and right of the head, respectively, while a central ( median ) ocellus is directed frontally.
32.
Nearly resembling the male, but on the posterior wings a space on each side of the large ocellus below the costal nervure is bright ferruginous.
33.
In some terrestrial insects ( e . g . some ants and cockroaches ), only two lateral ocelli are present : the median ocellus is absent.
34.
Tore wing with the ocellus, a brown ring surrounding it very broad and very broadly and diffusely produced downwards, discal and subterminal transverse fascial obscure.
35.
There is a dark dorsal line, a subdorsal purple-red band, edged with yellow on thoracic somites and a blue ocellus on 3rd somite.
36.
Juveniles are dark with a red nape, upper back and spiny dorsal fin, and a dark ocellus at the rear base of the dorsal fin.
37.
The forewing costal margin is suffused with buffy brown and there is an outcurved antemedial line followed by a broken ocellus in the cell at the subcosta.
38.
There is also a silvery white streak on the inner edge of the ocellus, which is continued to the inner margin as an olive double streak.
39.
When one FDX labeled pigment precursor cells is photoablated during the mid-neurula stage ( 15 hrs ) the other will almost always develop into an ocellus.
40.
The center of the ocellus is black or yellow, which is surrounded by concentric, alternating dark and light rings that may be either continuous or broken.
