scientific name    Furcula modesta    

common name     Modest Kitten

Deciduous woodland and shrub.

Adults are on the wing late May to July.

A medium-sized (3.5-4.0 cm. wingspan) grey-black and white moth, with a cream or light tan cast to the white areas of the forewings. A broad black band crosses the median area of the forewings. It usually narrows in the middle, and in many specimens is divided into two wedge-shaped patches. Modesta can be separated from other Furcula sp. by the absence of yellow or gold scaling on the forewing where the lines cross the veins. Male modesta can also be separated from the other species of Furcula by the diamond shape of the laterally flattened uncus.

life history
Adults are nocturnal and come to light. The larvae are solitary defoliators. There is a single brood which overwinters in the pupal stage.
