How does the common mormon see?
The common mormon (Papilio polytes) is a insect in the order Lepidoptera. Its eyes belong to the vision type Butterfly multispectral.
Measured in this species: motion (flicker fusion). One measured dial: a value other than colour or sharpness is measured in this species; colour and sharpness are not measured here. Every value below carries its evidence level and sources; nothing is typed by hand.

What stands out
- It has 5 colour receptor classes, including ultraviolet; people have 3.
- Its sharpest vision resolves 0.56 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 174.8 Hz, against 60 Hz for people in this dataset, so fast motion looks about 2.9 times slower to it.[8][9]
- Activity pattern: diurnal.
The six dials
Evidence levels: how the tiers work. "Measured" means a value measured in this species; "Estimated" values come from a close relative or an eye-size formula.
| Dial | Value | Evidence | Sources |
|---|---|---|---|
| Colour | Colour receptors 5 receptor classes: 360 nm (UVS), 400 nm (VS/SWS (violet)), 440 nm (SWS (blue)), 520 nm (MWS (green)), 600 nm (LWS (long)) receptor set of nearest measured relative Papilio xuthus (same genus Papilio) | Estimated | [1][2][3] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Estimated | ||
| Sharpness | Acuity 0.56 cycles per degree median of 1 relatives in genus Papilio: Papilio machaon | Estimated | [4] |
| Angle between facets 0.9° median of 1 relatives in genus Papilio: Papilio machaon | Estimated | [4] | |
| Eye type compound eye | |||
| Field of view | No value in the catalogue. | ||
| Sharp zones (foveas) | Number of foveas 0 median of 91 relatives in class Insecta: Empis prodromus, Rhamphomyia albidiventris, Rhamphomyia breviventris, Rhamphomyia maculipennis, Rhamphomyia marginata, Rhamphomyia murina | Group default | [5] |
| Fovea type none | Group default | [5] | |
| Night vision | Activity pattern diurnal mode of 7 relatives in genus Papilio: Papilio machaon, Papilio acheron, Papilio aegeus, Papilio maackii, Papilio protenor, Papilio xuthus | Estimated | [2][6] |
| Rods vs cones no rods (invertebrate photoreceptors) | Estimated | [2][6] | |
| Motion (flicker fusion) | Flicker fusion frequency 174.8 Hz median of 1 bright-light rows (behavioural/whole-eye ERG rows; all rows: [174.8]) | Measured | [7] |
