Morpho deidamia
Lepidoptera / Nymphalidae
Morpho deidamia has blue-banded upper wings and a complex brown underside. Amazonian research compares it with similarly patterned Morpho species through field experiments and genomic analyses.
Read the species account
The Amazonian account places the species in forest understory and lists records from Nicaragua and Costa Rica south through Panama, Colombia, Ecuador, Peru, Bolivia, Brazil, Suriname and Venezuela. [2]
Compiled host records include Inga laurina, Zygia latifolia, Machaerium seemannii and Iriartea deltoidea. Adults of both sexes visit fermented or rotten fruit, and the field guide records captures in fruit-baited traps. [2]
At a Peruvian Amazon study site, the daily activity period of Morpho deidamia overlapped with that of M. achilles. M. helenor was active at a different period, reducing temporal overlap with the other species. [3]
Moving-model experiments elicited interspecific territorial and courtship responses among similarly patterned Morpho butterflies at a Peruvian Amazon site. Genomic analyses supported genetic isolation among the species involved. [3]
Comparative genome assemblies revealed Z-chromosome rearrangements among Morpho deidamia, M. achilles and M. helenor. The authors proposed that these rearrangements could contribute to reproductive isolation between the sympatric species. [4]
The catalogue retains nominate deidamia and regional polybaptus and granadensis treatments. The museum guide also records Leonte deidamia as a historical combination. Museums Victoria specimen LEP 59155 documents Tingo Maria, Peru, on 20 May 1971 in the David Holmes collection, with Jose Schunke recorded as collector. [1][2][5]
The blue dorsal band contrasts with the brown ventral bands and eyespots. The field guide documents variation in the ventral pattern among regional forms. [2]
The illustration preserves the blue band within the dark upper-wing fields and the separate brown ventral pattern. Bold contours define the complete wing silhouette. [1][2]
Keep a physical specimen away from direct sunlight, heat and damp conditions. Avoid touching the scaled wing surfaces and maintain a closed, pest-free enclosure. [6]
What do adults feed on? Both sexes visit fermented or rotten fruit, including fruit baits used in field surveys. [2]
What distinguished the daily activity periods in the Peruvian study? Morpho deidamia overlapped with M. achilles; M. helenor was active at a different period. [3]
The specialist catalogue and Amazonian field guide establish the taxonomic treatment, pattern variation and feeding records. Field experiments and comparative genomes examine interactions among sympatric Morpho species. [1][2][3][4]
