If the effect is instead due to a resemblance to predators' eyes--an old and now disputed idea--that advantage could have nudged along the evolution of more realistic
eyespots on wings.
Species of Eurybia are usually large, mostly gray or brown butterflies, usually with an
eyespot at the end of the discal cell on the forewing and submarginal spots or occeli along the outer margin on both wings (Hall & Ahrenholz 2010); many species have iridescent scales at least on the hind wing.
Developing cysts are the average percentage of cysts having visibly faded
eyespots or an X-shaped excretory vesicle in metacercariae.
Developmental mode in opisthobranchs is most reliably documented when based on observations of the morphology of hatching veliger larvae--particularly the presence or absence of
eyespots and propodium--accompanied by measurements of egg size, embryonic period and temperature, and size and type of shell at hatching (Bonar 1978; Goddard 2004).
The cercariae were apharyngeate with pigmented
eyespots, a lightly spined body, dorsal and ventral fin folds on the full length of the tail furcae, 5 pairs of flame cells, and 3 pairs of penetration glands (Figure 3).
What begins as a thought of Eden transforms into nothingness and words, false
eyespots, shifts to a memory of two people lying in the sand, fused to sky and sea, two people who bequeathed to one another / a life that does not die like anything.
Eyespots are light-sensitive patches that allow simple organisms, such as jellyfish and some other algae, to sense their environments.

The moth, which can grow up to nine inches, is coloured brilliant yellow with huge red
eyespots.
Eyeless phyla are therefore degenerate or failed to develop
eyespots further.
Sundochernes differs from all other chernetid genera by the following combination of characters: flagellum with 3 blades; spermathecae with 2 thickened tubes with rounded terminal bulbs; legs without tactile setae; 1 pair of
eyespots present; vestitural setae generally small, dentate and clavate.
Ovigerous females collected from the West Branch of the Grand Calumet River and from Illinois, Lake County, Dead River mouth in Illinois Beach State Park included females with 1st instar and ova with
eyespots on the verge of eclosion (Table 1).
