|scientific name Archips negundana |
Most common in floodplains and river valleys where Manitoba Maple (Acer negundo) grows.
The forewing is pale straw yellow with a pattern that varies from being almost absent to dominating the forewing. The markings are mostly light orange-brown, typically forming broad bands in the basal and median areas that slant towards the anal angle. The postmedian line is normally present as a square patch on the costa and variably continues towards the anal angle. Dark brown markings can be present in small patches in the outer middle part of the basal and median patches, rarely in other parts of the wing. The hindwing is immaculate white.
The larva is uniformly pale green, the head is also pale but has some blackish near the ocelli. (MacKay 1962)
The larva is a leafroller. (MacKay 1962)
Not of concern. Localized outbreaks have occurred in Edmonton causing partial defoliation and extensive webbing on Manitoba Maple.
The larvae feed upon Manitoba Maple (Acer negundo), nettle (Urtica spp.), and honeysuckle (Lonicera spp.). (Freeman 1958; Razowski 1977)
From southern British Columbia to southern Quebec, south to California and Florida.
