scientific name    Metanema inatomaria    

common name     Yellow-lined Thorn, Pale Metanema

Deciduous and mixedwood forests and woodlands.

Late May to mid July, most common in June

Wings even grey (sometimes with slight dark speckling), and two straight, yellow-tan transverse lines on the forewing. Prominent black forewing discal spot, dark crescent along forewing margin near the apex, with a yellow border. Likely only to be confused with M. determinate, which has a contrasting dark band between the two forewing transverse lines, and has yellow scales within the dark discal spot (determinate has an all-black discal spot).

life history
The mottled grey and slightly flattened larva blends in well with tree bark. The winter is spent in the pupal stage, the larva cocooning in a bark crevice (Wagner et al 2001). Adults fly up when disturbed during the day, and also come to light at night.

Not of concern.

diet info
The preferred hosts are poplars (Populus spp.), and occasionally willows (Salix spp.). Coniferous hosts as indicated by several larval collections are likely in error and require confirmation (Prentice 1963).

East-central BC and southern NWT / YT east to Nova Scotia, south to MS, TX, and AZ (McGuffin 1987, Wagner et al. 2001).
