Both photographs are of the same specimen.
perspicua is one of several similar species of Datana that occur
in my area. Like many other species of Notodontidae, it tends to roll
its wings around its body or arch them over its body in a roof shape when at rest, as in the
above. According to Handfield (1999) and Covell (1984), Datana perspicua can
be distinguished by its pale yellowish forewing with its conspicuous brown
orbicular and reniform spots, likely the reason for giving it the common
name of Spotted Datana. The lines crossing the forewing are quite
sharply defined and reddish brown in color.
The larva of Datana
perspicua feeds on sumac.
The Ottawa area may be at or near the
northern limit of this species' range, and I have only seen or photographed Datana perspicua
once to date, in 2002 on 4 August.
