Gooseberry Caterpillar is the name applied to the larvæ of two different insects, both injurious to gooseberry and currant bushes. (1) the Magpie Moth (Abraxas grossulariata), appearing about midsummer, has usually a black head, yellow body, and white wings spotted  with black. (2) More destructive than the above is the larva of the Gooseberry Sawfly (Nematus ribesii), which plays havoc with the leaves of bushes. The larva is bluish green, with lack head, feet, tail, and spots, with twenty feet, and a length of about 3/4 of an inch when full grown.
