Fig. 6. Eye glow, pupillary pigments and lateral filtering pigments of H.
erato (AC) and V. atalanta (DF) from the
fronto-lateral eye region. (A) Eye glow of H. erato. Two classes of
ommatidia can be observed, one of them reflects yellow and the other red. (B)
Pupillary pigments at 190 µm from the cornea. (C) Lateral filtering
pigments at 370 µm from the cornea vary between ommatidia (circles a and b)
compared to the uniformly distributed pupillary pigments. (D) Eye glow of
V. atalanta. Only one orange reflecting class exists. (E) Pupillary
pigments at 180 µm from the cornea. (F). Pupillary pigments at 250 µm
from the cornea. Uniform pupillary pigment density between ommatidia can be
observed in all photoreceptor cells. Sections are 10 µm thick. Scale bars,
50 µm.
