Explanation of Names
DERIDENS: from the Latin "deridere" (to deride, mock, laugh at) - referring to the pattern on the forewings, which looks somewhat like a laughing face when the wings are held together at rest, and is the origin of the common name
Size
wingspan 38-48 mm
Identification
Adult: forewing pale gray, heavily shaded with darker gray; antemedial (AM) line black, sometimes clearly edged in white; postmedial (PM) line black, scalloped, and edged in white; AM and PM lines connected about halfway down the wing by black line that crosses median; this line partly surrounds a pale gray area bordering the dark-centered orbicular spot, giving the impression of an eye; reniform spot outlined in white, with a line of black filling; subterminal line jagged and shaded in black along inner edge; brownish-gray shading between subterminal (ST) line and black-dashed terminal line; hindwing light grayish-brown, slightly darker toward outer margin
