About the Poplar Kitten
The poplar kitten (Furcula bifida) is a species of moth in the family Notodontidae. The species was first described by Nikolaus Joseph Brahm in 1787. They are found throughout Europe and in North Africa, Mongolia, Kazakhstan and Xinjiang.
The forewings are grey, with a broad, dark grey central band and a cloud of the same colour towards the tips of the wings. The band is inwardly margined by an almost straight black line, and outwardly by a curved line; the third line is double, and curved towards the costa, forming the inner edge of the grey cloud, the lower part is wavy. The first black line is inwardly, and the second outwardly edged with ochreous, and preceding the first is a series of black dots. The hindwings are also white with brown dots along the margin. The wingspan is 44–48 mm. It differs from Furcula furcula in its generally larger size, but more especially in the shape of the black line forming the outer margin of the central band; this forms a clean curve whereas, in the alder kitten it is always more or less angled or dentate towards the front margin of the wings.
