Color vision of green and ultraviolet are universal among salticids but different species have different mechanisms of achieving certain color vision, and have a different extent to which color vision is inclusive of red. Adult males of the species E. culicivora have bright-red faces.
The ability to perceive green and ultraviolet light is common across all salticid species, but the way they process these colors varies between them.  E. culicivora males are particularly notable for their vibrant red facial coloration.
