Ochre Euchlaena

Not of concern

In Alberta adults fly from May to July, peaking from late May to mid June.

Southern interior BC east to Nova Scotia, south to FL, KY, MO and ID (McGuffin 1981, Wagner et al. 2001).

"A relatively pale, large Euchlaena. AM and PM lines more diiffuse than E. madusaria, black discal spots small but well defined. Outer third of forewing often contrasting and and slightly darker. Similar to E. tigrinaria, but lacks the black patches in the subterminal area of the wings. In eastern North America, the outer third of the wing is much darker than in western specimens; the western forms were described as Euchlaena albertanensis (Swett) but McGuffin (1981) considers these forms of marginaria. To complicate matters, Wagner et al. (2001) state that Canadian and northern US populations which have gone under the name marginaria may be a separate species from the douple-brooded marginaria of the southeastern US. "

Mixedwood and deciduous boreal forest.

The adults are nocturnal and are attracted to lights. The dark brown, mottled larva is a twig mimic, complete with two wart-like dorsal projections at the base of the abdomen (Wagner et al 2001). Ives & Wong (1988) also illustrate the larva.

The larvae feed on alder (Alnus sp.), white birch (Betula papyrifera) and willow (Salix sp.) in western Canada (Prentice 1963).

Euchlaena marginaria, the ochre euchlaena moth, is a moth of the family Geometridae. The species was first described by Charles Sedgwick Minot in 1869. It is found in North America, where it has been recorded from south-central British Columbia and Idaho to Nova Scotia and south to Florida and Missouri. The habitat consists of mixed wood and deciduous forests.

The wingspan is about 40 mm. The wings are light to dark brown with dark speckling. Adults are on wing from May to August in one generation in the north and two in the southern part of the range.

The larvae feed on Alnus, Salix, Spiraea, Amelanchier, Viburnum and Betula papyrifera. They are twig mimics. They are mottled dark brown.
