|Menelaus blue morpho|
Morpho menelaus, the Menelaus blue morpho, is an iridescent tropical butterfly of Central and South America. It has a wing span of 15 cm (5.9 in). The adult drinks juice from rotten fruit with its long proboscis, which is like a sucking tube. The adult males have brighter colours than the females.
Morpho menelaus is a very large butterfly, with a wingspan of approximately 138 mm.The forewing is concave at the outer edge. The upperside of wings are metallic blue.The underside is brown with a line of large ocelli at the base of the postdiscal area.
Morpho butterflies are Neotropical butterflies found mostly in Central America as well as Mexico and South America including Brazil, Costa Rica and Venezuela.
The subspecies are:
- Morpho menelaus menelaus Venezuela, Brazil, Surinam, Guyana The male is blue, but with extremely intense reflections. The female has only quite small white discal patches and the white spots on the discocellular are less developed than in the other races.
- Morpho menelaus alexandrovna Druce, 1874 Peru Male greeish blue with light spot before the apex, below which are placed three faint blue-white patches. Under surface dark chocolate-brown with grey scales near the distal border. Ocelli three times as large as in menelaus.

The nocturnal larvae are red-brown in colour with bright patches of lime-green or yellow. They are known to feed on Erythroxylum pulchrum and Machaerium, and are also highly cannibalistic. The Morpho butterfly drinks its food rather than eat it. It uses its proboscis (long, protruding mouth part) to drink sap and fruit juices. Morpho butterflies taste with sensors on their legs and taste-smell the air with their antennae. They butterflies feed on the juices of fermenting fruit with which they may also be lured. The inebriated butterflies wobble in flight and are easy to catch. Morphos will also feed on the bodily fluids of dead animals and on fungi. Therefore, Morpho butterflies may be important in dispersing fungal spores. The adults dwell in the forest canopy layer and rarely come near the understorey and forest floor layers; however, they have sometimes been observed flying near the ground in clearings.
It is similar in range and colouration to the Peleides Blue Morpho (Morpho peleides).
