(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.

Flies in the family Syrphidae are commonly known as hoverflies, flower flies, or syrphid flies.As their common names suggest, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.
