Insect morphology


Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history.

Basic Insect Morphology The following diagrams outline common characteristics found in insect anatomy, including detailed parts of wings, legs, and head. Three parts of an insect: head, thorax, abdomen. Humans have a head, torso (similar to thorax) and abdomen. Spiders have a combination of head and thorax (cephalothorax) and abdomen.

Insect Morphology MORPHOLOGY: THE STUDY OF FORM AND FUNCTION Insects are arthropods: Arthropoda: "jointed feet" Insecta: from insectum; to cut into General characteristics of arthropods: Segmented bodies Paired, segmented appendages Bilateral Symmetry Exoskeleton Dorsal heart and open circulatory system Ventral nerve cord

In a popular sense, "insect" usually refers to familiar pests or disease carriers, such as bedbugs, houseflies, clothes moths, Japanese beetles, aphids, mosquitoes, fleas, horseflies, and hornets, or to conspicuous groups, such as butterflies, moths, and beetles.

Insects that undergo three-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. [6] The higher level relationship of the insects is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22 to 28 in).

Insect Morphology General insect morphology is detailed in Snodgrass (1993), whereas a useful glossary of general entomology is provided by Torre-Bueno (1962) and was updated and revised by Nichols (1989).

Insect Morphology, Fig. 1. Schematic drawing of the integument layer of an insect. Full size image. The cuticle is the outermost layer, made of chitin-a long-chain polymer of N-acetylglucosamine-embedded in a protein matrix. The combination of these molecules is what grants an exoskeleton its rigidity.

Insect morphology is the study and description of the physical form of insects. The 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 , three pairs of legs, and mouthparts located outside of the head capsule.

About one million species have been described, and there may be as many as ten times that many yet to be identified. Of all creatures on earth, insects are the main consumers of plants. They also play a major role in the breakdown of plant and animal material and constitute a major food source for many other animals.

In the last decades a remarkable renaissance has materialized in insect morphology, mainly triggered by the development of new cutting-edge technologies. This is an exciting time for biological synthesis where the mysteries and data derived from genomes can be combined with centuries of data from morphology and development. And, now, more than ever, detailed knowledge of morphology is ...

External insect morphology. The Insect Body The insect body has a hard exoskeleton protecting a soft interior, and the bug anatomy can be divided into four main body parts: Insect Integument Insect head Insect thorax Insect abdomen Each of these is, in turn, composed of several smaller segments. Insect body parts and anatomy diagram

Although the functional morphology of insects remains a basic science, insect structures offer a variety of existing and potential applications in biomedical, structural, mechanical and aerospace engineering.

The phylogeny of insects is the fulcrum that underlies various macroevolutionary phenomena, such as the evolution of winged flight, parental care, cospeciation with plants, and morphological specializations for diverse modes of feeding, to name but a few. However, a stable insect phylogeny has historically remained elusive, even after the ...

Insect Morphology is presented for the purpose of instructing those interested in the identification of insects, particularly species with predatory or parasitic behavior. The evolutionary format used is to ease the means by which the various insect structures may be learned. The text is produced or paraphrased from cited references.

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.

The first part consists of insect morphology and introduces the concept of taxonomy, methods of insect collection, external and internal anatomy of the insects body parts and systems.

Not all social species of insects have distinct morphological differences between castes. For example, in the NeotropicalPulvilli are soft, cushionlike pads on the feet of insects and other arthropods, such as the housefly and ixodid ticks.
