|M. deidamia at a butterfly zoo in Hunawihr, France.|
The Deidamia Morpho (Morpho deidamia) is a Neotropical butterfly. It is found in Panama, Nicaragua, Costa Rica, Surinam, Bolivia, Colombia, Peru, Ecuador, and Brazil. It is a species group, which may be, or may not be several species. Many subspecies have been described.
Basal part of the upper surface in the males brilliant steel-blue, the distal area of both wings delicate light blue. But in the female the proximal region is darkened, being broadly black, though with intensive metallic reflection. Forewing with three white median dots, the light blue restricted to a relatively narrow median area.
The accepted subspecies are
- M. d. neoptolemus Wood, 1863 Brazil(Amazonas), Colombia, Peru Basal part of both wings black-brown, only distally with slight dark blue sheen. Female: The blue median band of both wings broader, darker but more glossy blue than in [nominate] deidamia. Under surface with somewhat less extended red submarginal patches, but with more copious white reticulation.
- M. d. granadensis C. & R. Felder,  Nicaragua, Panama, Colombia, Ecuador, Venezuela Upper surface similar to Morpho peleides, but the black distal border considerably more extended, the wings more rounded, the Morpho reflection deeper blue, and especially characterized by its large, light cinnamon-brown ringed ocelli, those on the forewing of uniform size, whilst on the hindwing the apical eye-spots far surpass the three closely approximated anal ocelli.
- M. d. polybaptus Butler, 1875 Nicaragua, Costa Rica, Panama The black distal area of the upper surface somewhat widened and the white subapical spot of the forewing more strongly expressed.On the under surface the whitish yellow anteterminal bands are more prominent and the bordering to the ocelli is of a finer bronzy greenish colour. Median band of the hindwing strongly elbowed, distally with a nose-shaped projection in the middle of the wing.
- M. d. pyrrhus Staudinger, 1887 Peru
- M. d. electra Röber, 1903 Bolivia A highly specialized local form from Bolivia with the hindwing decidedly more rounded and the forewing shorter. The upper surface is brilliant light blue, in certain lights with greenish gloss. The black distal margin very narrow, at the hinder angle of the forewing only about 2 mm. and at the apex about 10 mm., in the middle of the hindwing about 3 mm. in breadth. In the apex of the forewing are placed 2 white spots; the costal margin of the forewing is brown-black from the base to the discocellular, the white costal spot which follows about 10 mm. in length. The base of the wing only very slightly darkened. Under surface dark red-brown ; the form of the light markings quite similar to those of deidamia, but the eye-spots much smaller, margined with red-yellow (granadensis Fldr., but the subapical eye-spot of the hindwing is considerably larger in the latter), the distal-marginal markings are white (not yellow as in deidamia), the proximal silverwhite markings reduced, less continuous, and at the distal margin of the hindwing there are only small, narrow red longitudinal spots (no transverse band).
- M. d. hermione Röber, 1903 Colombia Differs from the typical deidamia of the Lower Amazon in having the black distal border much narrower; at the posterior angle of the forewing it is only about 2 mm. in breadth, but gradually widens and at the apex attains a breadth of about 1.5 mm.; the distal margin of the hindwing is about 3 mm. in breadth in the middle. The greenish blue median band is about 25 mm. in breadth, with its proximal boundary sharp and almost straight, the distal indistinct. The dark brown basal part is about 18 mm. in breadth and has only in the distal third a dark blue gloss. In the apex of the forewing are placed 2 small, distinct white spots and 1 very indistinct light one. At the costal margin of the forewing there is a small white spot. At the inner angle of the hind wing there are only traces of small reddish spots. The under surface is dark mahogany-brown, on the hindwing somewhat lighter about the veins, the light markings are in shape almost like those of deidamia, but are much less developed (narrower) and of the submarginal brick-red spots of the hindwing only slight traces are present.
- M. d. neoptolemus Fruhstorfer, 1907 Ecuador, Colombia Basal part of both wings black-brown, only distally with slight dark blue sheen. Female : the blue median band of both wings broader, darker but more glossy blue than in deidamia from Surmam and Obidos. Under surface with somewhat less extended red submarginal patches, but with more copious white reticulation.
