How does the autumn darter dragonfly see?
The autumn darter dragonfly (Sympetrum frequens) is a insect in the order Odonata. Its eyes belong to the vision type Hunter insect (dragonfly, mantis).
Measured in this species: colour. Measured colour or sharpness: a measured receptor set or acuity in this species; other dials come from relatives or group defaults. Every value below carries its evidence level and sources; nothing is typed by hand.

What stands out
- It has two colour receptor classes (a dichromat): reds and greens fall on one axis, as in red-green colour blindness in people.
- Its sharpest vision resolves 1.46 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 300 Hz, against 60 Hz for people in this dataset, so fast motion looks about 5 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.
