Hypoprepia inculta Hy. Edwards, 1882

93-0207

Identification

Adults

Hypoprepia inculta is a small to medium-sized (FW length 13–16 mm) gray tiger moth known only from the southeastern portion of the Pacific Northwest. The forewing is dull dark gray with lighter cubital vein and discal spot. The hindwing is pale whitish gray with a slight pink tint, darker anteriorly and at the margin. The head and thorax are dark gray like the forewings. The abdomen is lighter gray with an orange or pink tip.  The male antenna is biserrate.

Hypoprepia inculta is unlikely to be confused with any other tiger moth but resembles the noctuid moth Proxenus miranda in general color and lack of a distinct pattern. Hypoprepia inculta is dull with a pale cubital vein and pale pink hindwings. In contrast, P. miranda has a distinct sheen, lacks the pale vein, and has a gray hindwing.  Hypoprepia inculta has a pink tip to the abdomen which P. miranda lacks. They are distinctly different structurally, including the vein pattern (quadrifine in Hypoprepia and trifine in Proxenus (see glossary)).
