| The beautiful eyespots on butterfly wings are thought to rely on the principles described above, although involving more morphogens. |
| Pupae with low ecdysteroid levels develop into adults with small eyespots on their wings. |
| The male's head is blue and brown, and both sexes have bold, black eyespots at the napes of their necks. |
| Its wings are mottled brown, small eyespots dotting the scalloped edges here and there, small circles with tails on them. |
| However, pigmented eyespots are visible in wild-type larvae and late-stage embryos. |
| They do not have image-forming eyes, but many species have pigment cells and photoreceptors concentrated into eyespots. |
