Insect orders Anjali Bhushan

Coleoptera- beetle

Beetles are the largest group of living organisms known to science, bar none.

Over 300,000 species of beetles live on the earth and over 12,000 beetles live in the U.S. Beetles have a hard shell and four wings. Some beetles cause a lot of damage by eating crops, wood and food. Others help us by pollinating crops or eating harmful insects.

Lepidoptera- butterfly, caterpillar, moth

Butterflies and moths are part of the class of insects in the order Lepidoptera. Butterflies are flying insects with large scaly wings. Like all insects, they have six jointed legs and three body parts: the head, the thorax and the abdomen. The wings are attached to the thorax and they also have a pair of antennae, compound eyes and an exoskeleton.

The butterfly's body is covered by tiny sensory hairs. The four wings and the six legs of the butterfly are attached to the thorax. The thorax contains the muscles that make the legs and wings move.

Odonata- damesfly, dragonfly

It's easy to be fascinated by dragonflies. They were among the very first winged insects to evolve over 300 million years ago! Dragonflies belong to the order Odonata, characterized by large multifaceted eyes, two pairs of strong, transparent wings, and an elongated body.

The word Dragonfly and the family it belongs to, Odonata, have evolved from the many myths associated with Dragonflies and their taxonomic cousins, the Damselflies. The word Dragonfly has its source in the myth that Dragonflies were once Dragons. - See more at:

Hemiptera- cicadas, bed bugs, tree bugs

Cicadas belong to the order Hemiptera, suborder Auchenorrhyncha, superfamily Cicadoidea and families Cicadidae (the vast majority of cicadas) or Tettigarctidae (only two species). Leafhoppers, spittle bugs and jumping plant lice are close relatives of the cicada. Hemiptera are different from other insects in that both the nymph and adult forms have a beak (aka rostrum), which they use to suck fluids called xylem from plants. This is how they both eat and drink.

Cicadas are probably best known for their buzzing and clicking noises, which can be amplified by multitudes of insects into an overpowering hum. Males produce this species-specific noise with vibrating membranes on their abdomens. The sounds vary widely and some species are more musical than others. Though cicada noises may sound alike to humans, the insects use different calls to express alarm or attract mates.

Orthoptera- grasshoppers, cricket

How I am born: I go through three stages of development: egg, nymph and adult.

Grasshoppers are voracious feeders, consuming approximately one-half of their body weight per day. Both adults and nymphs cause damage by chewing on the leaves and stems of plants, and if infestations are severe, may defoliate entire fields. It is estimated that grasshoppers consume up to 25 percent of the available forage in the western United States annually.

Hymenoptera- bees, wasps, ants

All honeybees are social and cooperative insects. A hive's inhabitants are generally divided into three types.

There are about 20,000 different species of bees in the world. Bees live in colonies that contain the queen bee, the worker bee and the drone. The worker bee and the queen bee are both female, but only the queen bee can reproduce. All drones are male. Worker bees clean the hive, collecting pollen and nectar to feed the colony and they take care of the offspring. The drone’s only job is to mate with the queen. The queen’s only job is to lay eggs.
