Common NameWhite-dotted Prominent, Rough ProminentSeasonalityAdults are on the wing from the end of May to late July. Larvae from late June through early Sept.IdentificationA fairly large (3.8-5.9 cm. wingspan) orange, yellow-brown or rusty-orange moth, with prominent antemedian and postmedian lines. There are a pair of diagnostic small silvery white spots in the center of the pointed forewing. Male antennae are bipectinate and the females have simple antennae. Unlikely to be mistaken for any other Alberta moth. The similar Notodontid moth Datana ministra should also occur in southern Alberta; it can be separated from Nadata by it's maroon head and thorax.
