Buff-tailed bumblebee vision: the science and the numbers

Bombus terrestris · order Hymenoptera · Insects: all the numbers

The buff-tailed bumblebee has 3 colour receptor classes (347.5, 435 and 533 nm), one of them in the ultraviolet.[1] Its sharpest vision resolves 0.21 cycles per degree, against 63.75 for people in this dataset.[6]

The buff-tailed bumblebee (Bombus terrestris) is an insect in the order Hymenoptera. Its eyes belong to the vision type Bee, ant and locust UV trichromat: three receptor types (ultraviolet, blue and green, no red), a low-resolution compound eye and fast motion vision. Measured in this species: colour, sharpness and night vision. Measured core: measured values on at least 3 of the 6 dials.

This is a simulation built from published eye measurements, not what the animal experiences.

What stands out

  • It has three colour receptor classes, like most people, but one of them sees ultraviolet.
  • Its sharpest vision resolves 0.21 cycles per degree: the finest stripe pattern it can tell apart from grey.
  • 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. The last column gives the values for people from the same catalogue.
