From: Molecular variation across populations of a widespread North American firefly, Photinus pyralis, reveals that coding changes do not underlie flash color variation or associated visual sensitivity

Photinus pyralis sampling sites. Individuals used for sequencing were collected from 12 locations during May–July of 2011–2014. Shading shows states that have at least one record of P. pyralis presence [16, 18]. Populations are labeled with a 4-letter location code and colored by habitat type. Inset (top left) is the distribution of male mean peak emission spectrum (+/− 1 SE) across the populations, ordered by increasing wavelength (from yellow to more orange). Sample sizes for emission measurements are shown above. Lower left shows the ventral aspect of an adult male. This map was generated using the maps package in R
