Two new eye color mutants, Red-eye (re) and Vermillion eye (ve) arose spontaneously in laboratory stocks of Anopheles albimanus. Both mutants are recessive and expressed during the larval, pupal and adult stages. In individuals homozygous for Re, the eyes darken with age in the adult stage, but in Ve homozygotes there is no change in the bright red color. The loci for both mutants are on the right arm of chromosome 2, but the mutants are not allelic. Vermillion eye homozygotes are weak and a pure stock has been established and maintained with difficulty.
