Dolocucullia poolei can usually be distinguished from western Pacific Coast moths in other genera by its gray color and the touching zigzag antemedial and postmedial lines. In this region it resembles Cucullia intermedia or Cucullia florea oth of them lack the antemedial line. Dolocucullia poolei somewhat resembles Lacinipolia patalis, a very common moth in western Oregon and Washington during late spring. Compared to D. poolei, L. patalis has a shorter less pointed forewing with better defined markings that include a black basal dash and a reniform spot. It lacks the dark gray spot near the anal angle of D. poolei. Under magnification, the eyes of Dolocucullia are smooth and those of Lacinipolia are covered by short hairs.
Dolocucullia poolei is found in a variety of habitats. In the Pacific Northwest this species is often common in moist meadows of coastal rainforests within the Coast Range. It is particularly abundant in disturbed, open clear-cuts of the Oregon Coast Range. It also occurs less commonly in meadows of the Cascades.
Dolocucullia poolei occurs in western Oregon and Washington in the Pacific Northwest. It is most commonly encountered near the Pacific Coast—and is limited to the immediate coast at the northern end of its range on the Olympic Peninsula—but is found inland as far as the Cascade Crest in parts of Oregon.
The range of this species extends south in western California to near the border with Mexico. An isolated population is in the high Sierra Nevada range.
No specific information is known regarding larval foodplants of this species, but it probably feeds on herbaceous Asteraceae such as goldenrods (Solidago spp.) or gumweed (Grindelia spp.). The exotic tansy ragwort (Senecia jacobaeae) might be a foodplant in the Oregon Coast Range.
The flight period is late spring and summer in the Pacific Northwest, with records from late May to August. It is nocturnal and comes to light.
