Bees are a flower's best friends. Echoing previous studies from the northern part of the world, the Australian data, published today in the Proceedings of the Royal Society B, shows that flowers Down Under show the most color variance in the narrow spectra that insects are most sensitive to. This helps an insect distinguish flowers, remember their favorite, and return to it—good news for the plant. The results, now replicated on two continents, likely hold true elsewhere as well.
