The currant span-worm (Diastictis ribcaria) is a yellow, black- spotted looper, which often appears in such numbers on cur- rant and gooseberry bushes as to defoliate them very quickly. The moths are pale yellow, marked with irregular, dusky spots. Most of the moths of the subfamily Geometrinae are of a green color with the wings barred more or less distinctly with whitish lines.
