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.

Grasshoppers are herbivorous insects of the suborder Ceasefire in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change color and behavior at high population densities are called locusts. Recent estimates (Kevan 1982; G&uuml;nther, 1980, 1992; Otte 1994-1995; subsequent literature) indicate some 2,400 valid Caeliferan genera and about 11,000 valid species described to date. Many undescribed species exist, especially in tropical wet forests.

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.

The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The super family is made up of the ichneumon wasps (often inaccurately called "ichneumon flies"; family Ichneumonidae) and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.
