A Description and Examination of Fluorescence in Nine North American Firefly Species (Coleoptera: Lampyridae)

Table 1

Excitation and emission peak values for all species tested.

Species	Pronotum excitation wavelength	Pronotum emission wavelength	Lantern excitation wavelength	Lantern emission wavelength
Py linearis 1	372	500	535	590
Py linearis 2	427	592	367	492
Py angulata	421	531	375–434	535
Py dispersa	398	431	404	462
Photuris	368	466	364	505
Ph obscurellus	364	410	375	418
Ph greeni	537	601	370	424
Ph ignitus	436	587	468	539
Ph aquilonius	361	404	359	407
E. corrusca	536	581	NA	NA

Values represent the wavelength in nanometers of the most intense peak for each test. Where a range or multiple values are reported, the peak was especially broad or contained multiple peaks. Ellychnia do not possess a lantern and so these values are left blank.
