As used here, the term Insecta is synonymous with Ectognatha.Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound.

Dichotomous keys are very useful for identifying an organism as a member of a single, closely-related group of organisms. In many environments this is sufficient to fully identify the species. However, complications may arise if multiple closely-related species, which may have very similar characteristics, live in the same geographic area.

Phasmatodea Classification Essay

A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae.Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items. Two sets of muscles move the mandibles in the coronal plane: abductor muscles move insects' mandibles.

Phasmatodea Classification Essay

Insect respiration happens without lungs.There is a system of internal tubes and sacs through which gases diffuse or are actively pumped.Air is taken in through openings on the sides of the abdomen called spiracles. Oxygen gets to tissues that need it through their trachea (element 8 in diagram). Many insect larvae live in water. Many of those have gills that can extract oxygen dissolved in.

Orthoptera probably arose during the middle of the Carboniferous period. Most living members of this order are terrestrial herbivores with modified hind legs that are adapted for jumping. Slender, thickened front wings fold back over the abdomen to protect membranous, fan-shaped hind wings. Many species have the ability to make and detect sounds.

Insects for Human Consumption - ScienceDirect.

Abstract The phylogeny of insects has been both extensively studied and vigorously debated for over a century. A relatively accurate deep phylogeny had been produced by 1904. It was not substantially improved in topology until recently when phylogenomics settled many long-standing controversies. Intervening advances came instead through methodological improvement.The classification of insects has attempted to most effectively communicate information about this hyperdiverse lineage of life and, not surprisingly, has had a considerably rich historical development. This history can be coarsely segregated into four periods: the Pre-Linnean era, the first century spanning Linnaeus's to Darwin's, the Darwinian era up to the Cladistic Revolution, and the.Fun Insect Facts for Kids.

Both dragonflies and damselflies belong to the Odonata, which is a subgroup of insects, which in turn is a group of uniramian arthropods.Many characteristics distinguish Odonata from other groups of insects -- minute antennae, extremely large eyes (filling most of the head), two pairs of transparent membranous wings with many small veins, a long slender abdomen, an aquatic larval stage (nymph.Limited research and government funding are focused on mass-rearing or mass-processing methodologies of insects for human consumption. However, as mentioned in this chapter, several small companies are beginning to produce food products containing insects as well as develop methods of processing insects for use as safe, efficient food ingredients.
