How does the blowfly (Calliphora collini) see?
The blowfly (Calliphora collini) is a insect in the order Diptera. Its eyes belong to the vision type Fast fly (slow-motion world).
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 0.45 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 240 Hz, against 60 Hz for people in this dataset, so fast motion looks about 4 times slower to it.[7][8]
- 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: 335 nm (UVS), 357.5 nm (UVS), 460 nm (SWS (blue)), 490 nm (MWS (green)), 530 nm (MWS (green)) receptor set of nearest measured relative Calliphora vicina (same genus Calliphora) | Estimated | [1] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Estimated | ||
| Sharpness | Acuity 0.45 cycles per degree median of 1 relatives in genus Calliphora: Calliphora vicina | Estimated | [2] |
| Angle between facets 1.1° median of 1 relatives in genus Calliphora: Calliphora vicina | Estimated | [2] | |
| Eye type compound eye | |||
| Field of view | No value in the catalogue. | ||
| Sharp zones (foveas) | Number of foveas 0 median of 91 relatives in order Diptera: Empis prodromus, Rhamphomyia albidiventris, Rhamphomyia breviventris, Rhamphomyia maculipennis, Rhamphomyia marginata, Rhamphomyia murina | Group default | [3] |

| Rods vs cones no rods (invertebrate photoreceptors) | Group default | [4][5] | |
| Motion (flicker fusion) | Flicker fusion frequency 240 Hz median of 1 rows (no bright-light flag) (behavioural/whole-eye ERG rows; all rows: [240.0]) | Measured | [6] |
