Entomology is rooted in nearly all human cultures from prehistoric times, primarily in the context of agriculture (especially biological control and beekeeping). The natural Roman philosopher Pliny the Elder (23–79 CE) wrote a book on the kinds of insects, [ 4 ] while the scientist of Kufa , Ibn al-A'rābī (760–845 CE) wrote a book on ...
The human appendix averages 9 cm (3.5 in) in length, ranging from 5 to 35 cm (2.0 to 13.8 in). The diameter of the appendix is 6 mm (0.24 in), and more than 6 mm (0.24 in) is considered a thickened or inflamed appendix. The longest appendix ever removed was 26 cm (10 in) long. [3]
a central caudal filament, prolongation or median appendix dorsalis, which arises from the tip of the epiproct in certain apterygotes, many mayflies (Ephemeroptera), and a few fossil insects. [42] A similar structure in nymphal stoneflies is of uncertain homology.
The Archaeognatha are an order of apterygotes, known by various common names such as jumping bristletails.Among extant insect taxa they are some of the most evolutionarily primitive; they appeared in the Middle Devonian period at about the same time as the arachnids.
This glossary of entomology describes terms used in the formal study of insect species by entomologists.. When present, elytra of the Staphylinidae are markedly abbreviate. This fly in the genus Scaptomyza has clearly visible rows of para-sagittal acrostichal bristles on its thorax the alitrunk of aculeate Hymenoptera comprises the three thoracic segments, plus the propodeum, which strictly ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Andrew Delmar Hopkins (August 20, 1857 – September 22, 1948) was an American entomologist of the late 19th and early 20th centuries. Though self-taught, his scientific understanding of forest entomology was exceptional.
