About Xylophanes loelia Druce, 1878
Xylophanes loelia is a moth species first described by Druce in 1878. Its wingspan measures approximately 72 millimeters. This species is morphologically intermediate between Xylophanes libya and Xylophanes neoptolemus. Compared to Xylophanes libya, it has narrower hindwings. On the underside of its forewing, the first postmedian line is thin, continuous, more oblique, and less dark than in the related species. The second and third postmedian lines on the forewing underside are only faintly marked, while the fourth postmedian line is less conspicuous. The median band on the upper side of the hindwing is redder than in Xylophanes libya, though it is paler than the same band in Xylophanes neoptolemus. The marginal band on the hindwing upperside is more even in shape, narrower, and has a sharper definition. On the underside of the hindwing, the postmedian lines are straighter and not split into separate spots. The inner edge of the hindwing underside marginal band is also more even and continuous. This species is distributed from southwestern Belize through Costa Rica and Panama, extending south to Peru, Bolivia, and Argentina. It may also occur in Paraguay.
