Insects are cold blooded arthropods and represent 90% of all life forms on earth. They are among the most diverse groups of animals on the planet, with over 1 million different known species and as many as 9 million more yet to be discovered. Insects have three body parts: head, thorax and abdomen. They have three pairs of legs with six joints and they have two antennae. Bugs have external skeletons. These “exoskeletons” contain sense organs for sensing smell, sound, light, temperature, wind and pressure.Insects are cold blooded arthropods and represent 90% of all life forms on earth.

The Lampyridae are a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their use of bioluminescence to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red. About 2,000 species of fireflies are found in temperate and tropical environments. Many are in marshes or in wet, wooded areas where firefly babies have abundant sources of food. These larvae emit light and often are called "glowworms".


The Coccinellidae are a family of small beetles, commonly known as ladybugs in North America and ladybirds in Britain, Ireland, the Commonwealth and some parts of the southern United States. Entomologists in the United States prefer the names ladybird beetles or lady beetles, as these insects are not true bugs. Coccinellids are found worldwide, with over 5,000 known species. They are often yellow, orange, or scarlet with small black spots on their wing covers, with black legs, heads and antennae. Color patterns vary greatly, however. Depending on the species, they can have spots, stripes, or no markings at all. Many species are mostly, or entirely, black, dark gray, gray, or brown.


Beetles are a group of insects which are biologically classified in the order Coleoptera. The word "coleoptera" is from the Greek, koleos, meaning "sheath"; and pteron, meaning "wing", thus "sheathed wing". Most beetles have two pairs of wings, the front pair being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen. There are more beetles on the planet than other other animal. Almost 25% of all known types of animal life-forms are beetles. About 40% of all insect species are beetles (about 400,000 species), and new species are discovered frequently.


Centipedes are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are elongated creatures with series of body segments, with one pair of legs per body segment. Despite the name, centipedes can have a varying number of legs from under 20 to over 300. Centipedes have an odd number of pairs of legs, therefore there is no centipede with exactly 100 legs. They have a pair of venom claws and are a predominantly carnivorous. Centipedes normally have a drab coloration combining shades of brown and red.


Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax. There are nearly 20,000 known species of bees in seven to nine recognized families. They are found on every continent except Antarctica, and in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar as an energy source and pollen for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long tongue that enables them to obtain the nectar from flowers. They have antennae and two pairs of wings, the hind pair being the smaller of the two.


Ants are insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. There is an estimated 22,000 species of ants. Ants have colonized almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in most ecosystems and may form 15–25% of the terrestrial animal biomass. Their success in so many environments has been attributed to their social organization and their ability to modify habitats, tap resources, and defend themselves.


A dragonfly is an insect belonging to the suborder Anisoptera. Dragonflies have large multifaceted eyes, two pairs of strong transparent wings, sometimes with colored patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colors produced by structural coloration, making them conspicuous in flight. There are about 3000 species of dragonflies in the world today. Most are tropical, with a few species in temperate regions.


Butterflies are part of the class of insects in the order Lepidoptera. Adult butterflies have large, often brightly colored wings, and conspicuous, fluttering flight. The group comprises the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). Butterflies are the second largest group of pollinators, following bees. There are about 17,500 species of butterflies spread throughout the world. These beautiful animals undergo a fascinating metamorphosis which takes place in four stages: egg, caterpillar, pupa and adult.


Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support. Like other Arachnida a tarantula’s body comprises two main parts, the prosoma (or cephalothorax) and the opisthosoma (or abdomen). Tarantulas of various species occur in the southern and western parts of the United States, in Central America, and throughout South America. Other species occur variously throughout Africa, much of Asia and all of Australia. In Europe, some species occur in Spain, Portugal, Turkey, Italy, and Cyprus. Their natural habitats include savanna, grasslands such as the pampas, rainforests, deserts, scrubland, mountains, and cloud forests.


Scorpions are predatory arthropod animals of the order Scorpiones within the class Arachnida. They have eight legs and are easily recognized by a pair of grasping pincers (claws) and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. They have adapted to a wide range of environmental conditions and can now be found on all continents except Antarctica. Scorpions did not occur naturally in Great Britain, New Zealand and some of the islands in Oceania, but now have been accidentally introduced in some of these places by human trade and commerce. Scorpions number about 1,750 described species.


Spiders are invertebrates but are not considered insects because they only have two main body parts instead of three, eight legs instead of six and no antennae. Most spiders also have eight simple eyes, while insects have large, compound eyes. Some have no eyes and others have as many as 12. Spiders, along with ticks, mites, harvestmen and scorpions, are called arachnida. They are also classified into a special group called araneae because they have very slender waists compared to other arachnida.
