Common NameLintner's PebbleSeasonalityAdults emerge and are on the wing in early spring, late April and May.IdentificationA medium-size (3.3-4.0 cm. wingspan) grey and light tan moth, easily mistaken for the very similar G. severa. Separated from severa by the diffuse black blotch on the lower forewing just inside the median line in lintneri. The antennae are pectinate, broadly in males, narrowly in females. The three large species of Gluphisia can also be separated by male genitalic characters, notably the shape of the juxta, transtilla and uncus. In lintneri the uncus is shallowly excavated, the lobes of the transtilla are long and acute, and the juxta is broad and narrowly excavated, with the lobes broad and square. See also G. avimacula. There is also a rare form ("pretians") where the median area of the forewing is crossed by a wide, black contrasting band.

Life History
Lintner's Pebble is among the first moths to emerge from the pupae each spring. Adults are nocturnal and come readily to light. The larvae are solitary defoliators of aspen poplar. They overwinter as pupae.
Conservation
A widespread and fairly common species. No concerns.
Diet Info
No Alberta data available. Elsewhere in Canada aspen poplar (Populus tremuloides). (Prentice et al, 1962).
Range

Across much of southern Canada, east of the mountains. In Alberta, widespread in the Aspen Parkland and southern Boreal Forest regions, north to the northern Peace River district (northwest of Dixonville). There are few records for the foothills, and it is replaced in the mountains by G. severa.
