Almost nothing will differentiate it from the Ophrys aranifera/sphegodes (Spider Orchid) from a morphological point of view. Its labellum a little smaller perhaps? Carrying a caliper or being able to compare the 2 species in the same place is not the most convenient, even impossible since its singularity lies in its precocity because it flowers in the south of France from January most often but sometimes from the end of December. It is therefore officially only a subspecies or early regional variety, very similar to the Ophrys sphegodes (Spider Orchid).
