Grasshopper — Grasshoppers are herbivorous insects of the suborder Caelifera 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. The Grasshoppers have antennae that are almost always shorter than the body (sometimes filamentous), and short ovipositors. …

Glowworm — Glowworm (or glow-worm) is the common name for various different groups of insect larvae and adult larviform females which glow through bioluminescence. They may sometimes resemble worms, but all are insects (Arachnocampa being a fly and all the others being beetles). The major families are: Lampyridae (fireflies), found around the world. The wingless adult female is the glowworm …

Fly — Flies are insects of the Order Diptera (Greek: di = two, and pteron = wing), possessing a single pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. The common housefly is a true fly and is one of the most widely distributed animals. The presence of a single …

Flea — Flea is the common name for any of the small wingless insects of the order Siphonaptera (some authorities use the name Aphaniptera because it is older, but names above family rank need not follow the ICZN rules of priority, so most taxonomists use the more familiar name). Fleas are external parasites, living by hematophagy off the blood of …

Firefly — Lampyridae is a family in the beetle order Coleoptera, members of which are commonly called fireflies, lightning bugs or (ambiguously) “glow worms” due to their conspicuous nocturnal (or, more accurately, crepuscular) use of bioluminescence to attract mates or prey. Fireflies are capable of producing a “cold light” containing no ultraviolet or infrared rays, with a wavelength from 510 …

Earwig — Earwig is the common name given to the insect order Dermaptera characterized by membranous wings folded underneath short leathery forewings (hence the literal name of the order—“skin wings”). The abdomen extends well beyond the wings, and frequently, though not always, ends in a pair of forceps-like cerci. With about 1,800 recorded species in 10 families, the order is …

Dragonfly — A dragonfly is an insect belonging to the order Odonata, the suborder Epiprocta or, in the strict sense, the infraorder Anisoptera. It is characterized by large multifaceted eyes, two pairs of strong, transparent wings, and an elongated body. Dragonflies typically eat mosquitoes, midges and other small insects like flies, bees, and butterflies. They are usually found around lakes, …

Deerfly — Deer flies (Chrysops spp.) are flies of the family Tabanidae that can be pests of cattle, horses, and humans. Deer flies are similar to horse-flies, being smaller, having coloured eyes, and with dark bands across their wings. While female deer flies feed on blood, males instead collect pollen. When feeding, females use their knife-like mandibles and maxillae to …

Cricket — Crickets, family Gryllidae (also known as “true crickets”), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (family Tettigoniidae). They have somewhat flattened bodies and long antennae. There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure …

Cockroaches — Cockroaches (or simply “roaches”) are insects of the order Blattodea. This name derives from the Latin word for “cockroach”, blatta. Among the most well-known species are the American cockroach, Periplaneta americana, which is about 3 cm long, the German cockroach, Blattella germanica, about 1½ cm long, the Asian cockroach, Blattella asahinai, also about 1½ cm in length, and …
