Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The length of the forewings is 36–41 mm. It is intermediate in appearance between Xylophanes aristor and Xylophanes tersa. There is a weakly developed golden medial line on the tegula. The upperside of the thorax has a grey medial band, bordered laterally and divided medially by brown lines.
Only the discal spot, the basal section of the first postmedian line and the fourth postmedian line are standing out from the greyish-brown ground colour in most specimens. The pale yellow spots of the median band on the hindwing upperside are fewer and smaller than in Xylophanes tersa tersa and sometimes flushed with pink.
All of the plants Lewis collected in the first months of the Expedition were cached near the Missouri River to be retrieved on the return journey. The cache was completely destroyed by Missouri flood waters. Other collections were lost in varying ways, and we now have only 237 plants Lewis collected, 226 of which are in the Philadelphia ...
