Late Carboniferous and Early Permian insect orders include both several current, very long-lived groups and a number of Paleozoic forms.
Complete metamorphosis distinguishes the Endopterygota, which includes many of the most successful insect groups.
A number of highly successful insect groups evolved in conjunction with flowering plants, a powerful illustration of co-evolution.
During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm, making them far larger than any living insect.
Many entomologists are involved in various forms of pest control, often using insecticides, but more and more relying on methods of biological control.
Butterflies are an example of an insect that undergoes complete metamorphosis.
Insect larvae of various kinds are also commonly used as fishing bait.
Insect species were already diverse and highly specialized by this time, with fossil evidence reflecting the presence of more than half a dozen different orders.
The insect nervous system can be divided into a brain and a ventral nerve cord.
Research to discover these earliest insect ancestors in the fossil record continues.
At the end of the Ice Ages, estimated to have been around 10,500 B.C.E., the Sahara had become a green fertile valley, and its populations returned from the interior and coastal highlands in Sub-Saharan Africa.
Insect flight is not very well understood, relying heavily on turbulent atmospheric effects.
According to one European legend, the invention of felt is attributed to Saint James the apostle, who inserted tufts of wool in his sandals to soothe his feet during his evangelical travels.
Most people do not realize that food laws in many countries do not prohibit insect parts in food, but rather limit the quantity.
Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the European honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea and are presently considered a clade, called Anthophila.
A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera (from Greek ἄνισος anisos, "uneven" and πτερόν pteron, "wing", because the hindwing is broader than the forewing).
Centipedes and millipedes are not insects because they have more than six legs, but they are closely related invertebrates. When outdoors, these invertebrates are innocuous organisms, but they may be considered pests when they share living space with us.
