Sawfly — Sawflies make up the suborder Symphyta, a group of largely phytophagous insects in the order Hymenoptera. This group is an artificial assemblage of superfamilies (the overall group is paraphyletic), but the name is still in common use, and treated as a suborder, though it seems likely it will be phased out in future classifications. These superfamilies are regarded …

Silkworm — The silkworm is the larva or caterpillar of Bombyx mori (Latin: “silkworm of the mulberry tree”), the domesticated silkmoth. A moth in the family Bombycidae, it is very important economically as the producer of silk. It is entirely dependent on humans for its reproduction and no longer occurs naturally in the wild. Silk culture has been practised for …

Springtail — Springtails (Order Collembola) form the largest of the three orders of modern hexapods that are no longer considered to be insects (along with the Protura and Diplura). The three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, but they do not appear to be more closely related to one another than …

Stick Insect — The Phasmatodea are an order of insects, whose members are variously known as stick insects (in Europe), walking sticks (in the United States of America), ghost insects and leaf insects. The name is derived from the Greek “phasma” meaning an apparition or phantom, and refers to the resemblance of many species to sticks or leaves. Some species …

Tarantula — Tarantula is the common name for a group of “hairy” and often very large spiders belonging to the family Theraphosidae, of which approximately 900 species have been identified. Tarantulas hunt prey in both trees and on the ground. All tarantulas can emit silk, whether they be arboreal or terrestrial species. Arboreal species will typically reside in a silken …

Termite — Termites, sometimes known as white ants, are a group of social insects usually classified at the taxonomic rank of order Isoptera. Termites usually prefer to feed on dead plant material, generally in the form of wood, leaf litter, or soil, and about 10% of the 4,000 odd species (about 2,600 taxonomically known) are economically significant as pests that …

Thrips — Thrips (Order Thysanoptera) are tiny, slender insects with fringed wings (thus the scientific name, from the Greek thysanos (fringe) + pteron (wing)). Other common names for thrips include thunderflies, thunderbugs, storm flies and corn lice. Thrips species feed on a large variety of sources both plant and animal by puncturing them and sucking up the contents. A large …

Wasp — A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee or ant. The suborder Symphyta includes the sawflies and wood wasps, which differ from members of Apocrita by having a broader connection between the mesosoma and metasoma. In addition to this, Symphyta larvae are mostly herbivorous and “caterpillar like”, whereas those …

Water Beetle — A water beetle is a beetle adapted to living in water. A number of different types are known, nearly all living in or on fresh water. The few marine species tend to live in the intertidal zone. Many water beetles carry an air bubble underneath their abdomens, which both provides an air supply, and prevents water from …

Weevil — A weevil is any beetle from the Curculionoidea superfamily. They are usually small, less than 6 mm (� inch), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). Some other beetles, although not closely related, …
