Editing Tsetse fly (section)

===Anatomy===
Like all other [[insect]]s, tsetse flies have an adult body comprising three visibly distinct parts: the head, the thorax, and the abdomen.

The head has large eyes, distinctly separated on each side, and a distinct, forward-pointing proboscis attached underneath by a large bulb. The thorax is large, made of three fused segments. Three pairs of legs are attached to the thorax, as are two wings and two [[halteres]]. The abdomen is short but wide and changes dramatically in volume during feeding.

The internal anatomy of the tsetse is fairly typical of the [[insect]]s; the [[crop (anatomy)|crop]] is large enough to accommodate a huge increase in size during feeding, as tsetse can take a blood meal equal in weight to themselves. The [[dipteran crop]] is heavily understudied, with ''Glossina'' being one of the few genera having relatively reliable information available: Moloo and Kutuza 1970 for ''G. brevipalpis'' (including its innervation) and Langley 1965 for ''G. morsitans''.<ref name="Stoffolano-Haselton-2013" /> The reproductive tract of adult females includes a [[uterus]], which can become large enough to hold the third-instar [[larva]] at the end of each [[pregnancy]].[[File:Dipteran-fly-structure.jpg|thumb|upright=1.75|1-Complex mouthparts, 2-Paired antennae, 3-Head, 4-Compound eye, 5-Thorax, 6-Open tube heart, 7-Salivary gland, 8-One pair of wings, 9-Halter, 10-Excretory (Malpighian) tube, 11-Gut, 12-Ovary (or testis), 13-Abdomen, 14-Legs (3 pairs), 15-Thoracic ganglion of nervous system, 16-Spiracle opening to respiratory tube (trachea)]]

Most tsetse flies are, physically, very tough. Houseflies, and even horseflies, are easily killed with a flyswatter, for example; a great deal of effort is needed to crush a tsetse fly.<ref name="Mavhunga-2018">{{cite book |author=[[Clapperton Chakanetsa Mavhunga]] |url=https://mitpress.universitypressscholarship.com/view/10.7551/mitpress/9780262535021.001.0001/upso-9780262535021-chapter-001 |title=The Mobile Workshop: The Tsetse Fly and African Knowledge Production |year=2018 |isbn=978-0-262-53502-1 |doi=10.7551/mitpress/9780262535021.001.0001}}</ref>
