byrsotria rothi or fumigata? or both

[Kevin]

I bought a group that were suppose to be Byrsotria rothi but the size and color between a few of them leads me to believe there mixed. Is the black one a male rothi? and the light brown one a male fumigata?

Any input would be appreciated.....if they are 2 species I would like to separate them.

From my experience, they are both rothi; Just two different color strains.

The wings of the male B. fumigata look very different.

So there both male rothi? Its just weird since there is a big size difference as well as the color.
