'Night Wings' is missing its ploidy in the AHS registered daylily database. However, it has 22 registered offspring. Of those, 21 are registered as tetraploid and one is registered as a diploid. However, that offspring, 'Jupiter Light House', involves a cross with 'Ed Murray'. Although 'Jupiter Light House' is registered as a diploid, it is probably either a tetraploid or triploid, as 'Ed Murray' crosses with tetraploids. 'Night Wings' almost certainly crosses as a tetraploid.
