hi Cath nice crossover I had it id-ed first D. semilunulata then changed my mind to D. pardina then was in doubt when your id came through. Still: how to distinquish between the 2 species? thanks W
D. semilunulata flowers much later. D. pardina finished a couple of weeks ago. D. semilunulata is much more orange with lighter blotches, and has rounder labellum sidelobes than D. pardina.
