Description: (Ophrys speculumSN|35004]]SN|35001]] (syn: Ophrys ciliataSN|35001]]SN|35004]]) is a perennial herb, growing from a tuber reaching a height of 5-25 cm. The flowers are highly visible as the light reflects off the speculum in the centre of the lip that is a bright iridescent purple/blue in colour and very glossy. The lip is three-lobed and bordered by a greenish-yellow border which is surrounded by a band of thick velvety hairs which are reddish brown. The sepals and petals are green and marked with violet spots or stripes. Its insect- mimic flowers emit optical and olfactory stimuli to attract male wasps (Dasyscolia ciliata) looking to mate. The flower of this orchid mimics the top of the female insect's abdomen: blue iridescent wings folded over a hairy body. It also emits a stimulating scent compound attractive to the wasp. Although this is a case of mistaken identity for the wasp, it's a successful case of pollination for the flower. [2]
Leaves: Basal leaves oblong with obtuse apex, cauline leaves (of the stem) lanceolate with acute apex.
Inflorescence: Sparse, usually few flowered (2-8 flowers).
Flowers: Sepals oblong, obtuse, green with two reddish-brown streaks, the lateral reclined downwards, the median one curved on the ginostemium with a thickened margin. Petals about half as long a the sepals, ribbon-shaped, brown, pubescent, truncated at the apex. Labellum trilobed, up to 16 mm long, entirely surrounded by thick and long reddish-brown hairs, lateral lobes inserted in the basal half, more or less triangular, median lobe much larger, obovate, occupied almost entirely by the glabrous, glossy, blue macula, violet with metallic reflections, with yellow-orange border; Ginostemium short, and obtuse.
