Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...
