Insects live in a world of motion. This leaf-footed bug climbs wind blown grass and flies off. Insects (from Latin insectum) are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen ), three pairs of jointed legs ...

Beetles are insects that form the order Coleoptera ( / koʊliːˈɒptərə / ), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described ...

Insects have exoskeletons (skeletons on the outside). Their skeletons are made out of thin, hard pieces or plates, like armour, made of chitin. All together, these pieces make a hard layer around the insect's body. The exoskeleton protects the insect. The body of an insect has three main parts: a head, a thorax, and an abdomen. On the head are an i...
Just like our muscles connect to our bones to make us walk and stand up, the muscles of an insect connect to the exoskeleton to make it walk and move. Their muscles are on the insideof their skeleton. Insects are cold-blooded, which means that they cannot control their body temperature. This means that insects are not good at surviving the cold, at...
Origin of insects
The oldest known insect fossil is the Devonian Rhyniognatha, from the 411 million year old Rhynie chert. It may have superficially resembled a modern-day silverfish insect. This species already possessed mandibles of a type associated with winged insects, suggesting that wings may already have evolved at this time. Thus, anatomical records suggest the first insects may have appeared earlier, in the Silurian period. Genomic analysis puts their origin even further back in the Ordovicianperiod....
Origin of wings
In 2008, researchers uncovered what they believe is the world's oldest known full-body impression of a primitive flying insect, a 300 million-year-old specimen from the Carboniferousperiod. The origin of insect flightis unclear, since the earliest known winged insects appear to have been capable fliers. Some extinct insects had an additional pair of winglets attaching to the first segment of the thorax, for a total of three pairs. It seems the insects were not a particularly successful group...
Different kinds of insects are put into groups called orders. There are about 29 insect orders. The biggest insect orders are listed below: 1. Beetles(order Coleoptera) have the front pair of wings changed into a hard shell to protect the back wings. 2. Butterflies and moths (order Lepidoptera) have large, often colourful wings. 3. Flies(order Dipt...

Some insects can be pests to people in different ways. Some are parasites, such as lice and bed bugs. Some of these parasite insects spread diseases, for example mosquitoes spread malaria. Many insects eat agricultural products (plants meant for people to eat). Locustssare an example of pest insects that eat plants in agriculture. Some insects are ...

Insects are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species.
May 3, 2024 · Insect, any member of the class Insecta, the largest class of phylum Arthropoda. Insects have segmented bodies, jointed legs, and exoskeletons. They are distinguished from other arthropods by their body, which has three major regions: the head, the three-segmented thorax, and the many-segmented abdomen.

Coccinellidae ( / ˌkɒksɪˈnɛlɪdiː /) [3] is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs.
