Hawkmoths can still see colors at night

For the first time, scientists have detailed evidence that an animal can see color by starlight. People lose color discrimination in such dimness, but hawkmoths aced tests of color recognition at night.

Some older studies suggested that goldfish and a different moth see colors in dim light, but Almut Kelber of Lund University in Sweden and his colleagues focused on the Deilephila elpenor hawkmoth, which collects nectar during the darkest hours of the night in Europe.
