Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP -i- DOP -tər-ə, from Ancient Greek lepís “scale” + pterón “wing”) is an order of insects that includes butterflies and moths (both are called lepidopterans). About , species of the Lepidoptera are described, in families and 46 superfamilies, 10 per cent of the total described species of living organisms. It is one of Class: Insecta. The most recent understanding of the evolution of insects is based on studies of the following branches of science: molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology, bioinformatics and scientific computing. It is estimated that the class of insects originated on Earth about million years ago, in the Ordovician, at about the same time terrestrial Dicondylia: Apterygota, -ThysanuraMonura.
Aside from the Holometabola, Odonata is the insect group with the greatest variation between the habitat preferences of the nymphs and the adult. The adult is an elegant and agile aerial predator whereas the predaceous nymphs are aquatic e.g. . The ontogenetic development of the thoracic morphology of Odonata has not been extensively by: Identify the appendages located in the thorax and its parts 4. Differentiate insect’s wing modifications and adaptations. MATERIALS: Representative pinned specimens Hand lens Stereomicroscope Procedure: 1. With reference to the lecture notes and drawings from the book, study the parts of the thorax (prothorax, mesothorax and metathorax) 2.
The locomotive power for insects comes from the thorax and its appendage (legs and wings). The anatomy of the thorax is illustrated above. Insect locomotion is characterised by two main advancements: the jointed limbs characteristic of arthropods that allowed the arthropods to colonise land and flight. Pull the head slightly forward, away from the thorax to see the narrow curved occiput. This will also reveal the soft, unsclerotized cervix, or neck, connecting head with thorax. The large opening in the posterior head capsule, between head and thorax and covered by the cervix, is the foramen magnum.

Morphology and Mechanism of the Insect Thorax: Smithsonian Miscellaneous Collections, V80, Author: Robert Evans Snodgrass. Insect morphology is the study and description of the physical form of terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history.
Three physical features separate insects from other arthropods: they have a body divided into three regions (head, thorax, and abdomen), have three pairs of legs, and mouthparts located. - Bingham's issued volumes on "Hymenoptera' (Ants, bees and wasps). Since than volumes on other groups of insects like Coleoptera (beetles), Hemiptera (bugs), Odonata (dragenfly and damselfly), etc., were published.
- Indian Museum, Calcutta published the Indian Museum Notes in five volumes. - which contributed much on economic entomology and applied entomology in Size: 9MB. Insects or Insecta (from Latin insectum) are hexapod invertebrates and the largest group within the arthropod tions and circumscriptions vary; usually, insects comprise a class within the Arthropoda.
As used here, the term Insecta is synonymous with s have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound. The body is comprised of 3 distinct body regions -- head, thorax, and abdomen The thorax of adults bears 3 pairs of legs and 2 pairs of wings The "breathing" system is comprised of air tubes A look at the outside of an insect: The exoskeleton is comprised of sclerites: hardened plates File Size: KB.
The Insect Thorax and Abdomen In the simplest terms, the thorax is the locomotory centre of the insect since all six legs and the wings are found there.
The largest muscles are also found in the thorax. The thorax is a box-like structure with extensive internal cuticular cross bracing. It also sports numerous. This is the most important textbook of insect morphology ever written in English, by the foremost arthropod morphologist of this century (Thurman a, Richards ).
Robert Evans Snodgrass () began his morphological research as a freshman at Standford University. After receiving his A. Insect Pheromone Biochemistry and Molecular Biology covers how insects produce pheromones and how they detect pheromones and plant volatiles.
Since insects rely on pheromone detection for both feeding and breeding, a better understanding of insect olfaction and pheromone biosynthesis could help curb the behavior of pests without the use of.

Still the standard reference in the English language, Principles of Insect Morphology is considered the author's masterpiece. Morphology is concerned with the form and function of anatomical structure; because anatomy is an expression of organic evolution, morphology seeks to investigate possible explanations for organic diversification observed in nature.
Beforeinsect morphology focused on naming and describing anatomical by: 6. Apart from its peculiar morphology, Epiophlebia also puzzled odonatologists by its distribution.

In the Dutch naturalist, anatomist and microscopist Jan Swammerdam (–) published his remarkable book Historia Insectorum Generalis (“The Natural History of Insects”), focused on the development and metamorphosis of insects Cited by: Ryuichi Matsuda (July 8, – J ) was a Japanese entomologist.
He obtained his PhD in entomology from Stanford worked at the Biosystematics Research Institute of Canada. He wrote several works on the comparative morphology of insects. He is most well known for his controversial book Animal Evolution in Changing Environments (). • 3 body regions (head, thorax, abdomen) • Zero, 1, or 2 pairs of wings • 1 pair of antennae and Guide To Insect Identification to Know the Immature Insects •Insects and Diseases of Woody Plants of the Central Rockies* •Pests of the West * Book title list hand-out.

The thorax provides structural support for the legs (three pairs) and, if present, for one or two pairs of wings.
