Euthyatira pudens, the dogwood thyatirid moth or peach-blossom moth, is a moth of the family Drepanidae. It is found in North America, where it ranges across southern Canada, south to the Gulf of Mexico. The habitat consists of moist forests and riparian zones along creeks at low to middle elevations.
The wingspan is 20-45 mm. There are two distinct forms. The common form has pink-white patches at the base, along the costa and at the apex. There is a coppery-brown spot at the anal angle. The hindwings are brown. Form pennsylvanica is darker, blackish near the wing base, and does not have the pink-white patches. Adults are on wing in spring in one generation per year.
The forewing is long and relatively narrow, with a pointed apex and slightly scalloped outer margin. It appears slightly curved because its costal margin is convex, and its trailing margin is slightly concave. The ground color is gray, usually with tan along the trailing margin, with a dusting of white in the cell and anterior subterminal area, and darker gray on the veins near the outer margin. Prominent, light pink patches bordered by darker gray are located in the basal area, anterior median area, and at the apex. The black transverse lines are faint except where they abut the pink areas. The fringe is gray, sometimes checkered with light pink. The orbicular and reniform spots are black filled with light pink, are small, and are closely positioned to the point where they are fused in some specimens. The hindwing is pale brownish gray with light gray thin discal spot, median band, and terminal area. The thorax has a dark brown-gray collar which contrast with light pink areas on the anterior tegulae. The male antenna is filiform.
Members of the family Thyatiridae resemble noctuid moths in shape but are more closely related to hook-winged moths (Drepanidae) and inchworm moths (Geometridae).
The larvae feed on Cornus species. The larvae are dark gray black with a white ventral area.
