How does the Australian emperor dragonfly see?
The Australian emperor dragonfly (Anax papuensis) is a insect in the order Odonata. Its eyes belong to the vision type Hunter insect (dragonfly, mantis).
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 4 colour receptor classes, including ultraviolet; people have 3.
- Its sharpest vision resolves 2.08 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 57.1 Hz, against 60 Hz for people in this dataset, so fast motion looks about the same.[6][7]
- 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 4 receptor classes: 354 nm (UVS), 380 nm (UVS), 442 nm (SWS (blue)), 503 nm (MWS (green)) receptor set of nearest measured relative Anax junius (same genus Anax) | Estimated | [1][2] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Estimated | ||
| Sharpness | Acuity 2.08 cycles per degree median of 1 relatives in genus Anax: Anax junius | Estimated | [3] |
| Angle between facets 0.24° median of 1 relatives in genus Anax: Anax junius | Estimated | [3] | |
| Eye type compound eye | |||
