both their range overlap in our area. so that's 1 plus point.
secondly, the hybrid is not very spectacular looking, so demand probably isn't sky high. thats another plus point.
thirdly, it looks like a female - male transitioning melanospilos, and not some hybrid. so supplier may not know. 3rd plus point.
we may get to see it afterall one day. but it's very rare i guess.
