|scientific name Digrammia denticulata |
common name Striped Granite
Dry woodlands and aspen parkland.
Late May to early August, peaking in mid to late June.
Light grey in colour, with a whitish ground colour; three black wedges along the forewing costa, sometimes with a fourth subapical wedge. Forewing AM, PM and median band developed equally, not dark and bold. Distinguished by the absence of the bold AM and PM lines, and a lighter ground colour than most other Digrammia, giving it a more contrasting appearance.
The life history and immature stages are incompletely known; the egg and first instar larva are described by McGuffin (1972). Adults come to light. Handfield (1999) states that this is a species of open, mesic woodlands and bogs, but it in Alberta it occurs in much drier habitats. Perhaps more than one species is included under this name.
Not of concern.

Yukon to Ontario, south to CA and IL (McGuffin 1972). Despite the wide distribution of this species, records are lacking for much of boreal transcontinental Canada.
