Twin-spotted Sphinx

It has a wingspan of 1+3⁄4–3+1⁄4 inches (4.5–8.3 cm), with the outer margins of the forewings unevenly scalloped, but with the coastal margin of the hindwings being almost straight. Males have gray with black and white markings on their forewings, while females are yellowish brown with dark brown and white markings. Both sexes have red hindwings with a pale yellow border. Sometimes a blue patch may appear as a single eyespot or it may be divided by black bands, creating two or three eyespots. Adult moths are nocturnal and do not feed. Larvae are polyphageous (eat a wide variety of plants); known hosts include willow (Salix), poplar (Populus), birch (Betula), ash (Fraxinus), elm (Ulmus), apple (Malus), and plums (Prunus).
