Four-spotted Fungus Moth (Metalectra quadrisignata) wings less mottled, and covered extensively by medium grayish-brown ground color; diffuse blackish line runs through black reniform spot but there is no broad blackish band crossing wing in median area - as there is in M. discalis (compare images of the two species at CBIF, and note similarity to light form of M. discalis at MPG, showing a paler yellowish ground color and broader blackish band across median area of forewing)
