Species strigilis (Marbled Minor - Hodges#9415.1)
Hodges Number
9415.1
Numbers
locally common in southern Quebec along St. Lawrence River [Handfield, 1999]; status elsewhere unknown, but may be expanding its North American range
Size
wingspan 22-28 mm
Identification
Adult: forewing medial area yellowish-brown to yellowish-gray, sometimes with reddish tint; PM line a sinuate series of black-edged white scallops, bordered distally by whitish or pale gray subterminal area; reniform, orbicular, and claviform spots filled with ground color and outlined in black; basal area dark gray, bordered distally by scalloped white AM line; posterior portion of thorax brownish-orange dorsally; melanic specimens with mostly black forewings are relatively common; hindwing grayish-brown with pale fringe
Range
native to Europe; recent accidental introduction to eastern North America; Internet records from Quebec and Massachusetts
Habitat
grassy areas, open spaces, suburbs near homes or other buildings; adults are nocturnal and come to light and bait [Handfield, 1999]
Season
adults fly from May to July
Food
larvae feed inside roots and stems of various grasses (Orchardgrass (Dactylis glomerata) and Quackgrass (Elymus [=Agropyron] repens) are foodplants in England; both of these grass species are widespread in North America); also reported on Poa species
Remarks
First North American record from Quebec on 15 July 1990 [Handfield, 1999]

Mikkola and Lafontaine (1994) suggest that the turf and soil being picked up in shipyards, e.g., on the bottoms of large shipping containers, could be responsible for the recent introduction of several Palearctic moth species, including O. strigilis.

Bridgham's Brocade (Oligia bridghamii) forewing has reddish medial area, contrasting reniform and orbicular spots, and no claviform spot (compare images of both species at CBIF)
