Common NameDogwood Thyatirid, Peach-blossom Moth SeasonalityIn Alberta it is on the wing in spring, from late April through early June. IdentificationA medium-sized moth (4.0-4.5 cm wingspan). It occurs in two very different appearing forms, with the dark form by far the less common of the two. The more common "normal" form has pink-white patches at the base, midpoint along the costa and at the apex, and a coppery brown spot at the anal angle. The hindwings are brown with an indistinct discal mark. The less common form (pennsylvanica) is much darker, blackish near the wing base, and entirely lacks the pink-white patches. The outline of the apical patch is visible, as is the coppery-brown spot at the anal angle. The most prominent marking is the short black line on the lower edge of the apical patch. Antennae are filiform and the sexes are similar. The normal form is unlikely to be mistaken for any other Alberta moth.

Life History This is one of the first moths to emerge in the spring. The adults are attracted to light. Conservation A fairly common, widespread species; no concerns. Diet Info The larvae use various dogwoods (Cornus sp.) as hosts. Jones (1951) also lists Rubus sp. (blackberry and raspberry) as hosts of pudens, but this is unlikely and should be verified. Range
