Given the recent emphasis on Lepidoptera wing color and temperature in
macroecology, we briefly describe known drivers of wing color and outline
the use of images for understanding color variation across space and time.
As a case study, we quantify wing color using museum specimens of the
non-migratory Puerto Rican monarch. In contrast to recent findings, we
report darker individuals in coastal habitats, underscoring the need to
include other selection factors. We detail how international digitization
initiatives can resolve this paradox by adopting standards and protocols
for high-throughput image analysis.
Puerto Rican Monarch Wing TraitsWing traits measured on the Puerto Rican
monarch from the Stuart J. Ramos Collection at the McGuire Center for
Lepidoptera and Biodiversity at the Florida Museum of Natural History
(MGCL). Wing traits include: forewing length (cm), hue, saturation,
brightness, and percent melanization. Ancillary data including
georeferenced latitude (decimalLatitude) and longitude (decimalLongitude),
town, and day, month, year of collection as well as the MGCL identifier
are also provided. Habitat types (coastal or montane) are
identified.MonarchTraits.csv
