About Dejongia lobidactylus (Fitch, 1854)
Dejongia lobidactylus is a moth species that belongs to the Pterophoridae family. It can be found in the north-eastern United States and central Canada, specifically in the provinces of Quebec and Ontario. This moth has a wingspan ranging from 17 to 20 millimetres (0.67 to 0.79 inches). Its head is greyish-brown, marked with a white line above each eye. The thorax is brown, and it is noticeably lighter in color towards the posterior end. The abdomen is dark brown, with diverging white lines present on some of its segments. The forewings are colored dark cinnamon brown. An oblique pale yellow or white stripe crosses the basal third of the first forewing lobe, cutting through the brown fringe on both sides of the lobe. Traces of this stripe may sometimes be visible on the second lobe, most noticeably in the fringe along the hind margin. Indications of a second stripe can also be seen on the outer third of the lobes, shown by a small number of light scales and white coloring in the fringes. The fringes are dark elsewhere, except at the apical end of the costa. The hindwings and their associated fringes are dark brown. There is a cluster of black scales in the hind fringe of the hindwing a little beyond the middle of the fringe; this cluster is preceded by white scales, and the fringe at the apex of the hindwing is also white. Adult Dejongia lobidactylus are active in flight from June through August. Recorded observations note that the larvae feed on the terminal buds of Solidago species.
