Morpho (genus)
Neotropical butterflies with iridescent blue wings from structural coloration.
Last updated
The genus Morpho consists of Neotropical butterflies whose range primarily covers South America, Mexico, and Central America.[1] Within this genus, over 29 species and 147 subspecies are recognized; the smallest species, M. rhodopteron, has a 7.5 cm wingspan, while the largest, M. hecuba (the sunset morpho), reaches 20 cm.[1] The term "morpho" serves as both a genus name and an epithet, with its meaning being "changed" or "modified".[2]

Key facts and history
The genus Morpho was established by Fabricius in 1807.[3] These colors result from structural coloration, not pigmentation, through light interference in microscopic wing scales.[4] The blue morpho’s wings are bright blue edged with black, while the underside is dull brown with eyespots for camouflage.[5] Blue morphos live in tropical forests from Mexico to Colombia.[5]
The entire life cycle from egg to adult lasts about 69–75 days.[6] Humans also threaten them because artists and collectors capture them for display.[2][5] A metallic, shimmering appearance in shades of blue and green is characteristic of many morpho butterflies.[4]
What the cited sources add
The "Blue Morpho Butterfly" account notes that blue morphos taste fruit with sensors on their legs and use their antennae to "taste-smell" the air.[5] That same source states that pilots flying over rainforests have seen large groups of blue morphos above the treetops warming themselves in the sun.[5] Moulton’s article describes the morpho genus as "huge neotropical butterflies with a variety of intense blues and cyans".[7] The Savela database lists numerous species and subspecies, including the hercules species-group and the hecuba species-group.[3]
That database also records that Morpho hecuba was originally described by Linnaeus in 1771.[3]
