(4)The definitive host is either rats or raccoons and therefore, in this step the Acanthocephala matures in the small intestine. (5)Lastly, the Acanthocephala matures and also produces eggs inside the definitive host (Centers for Disease Control and Prevention, 2019).
The common names of the Coreidae vary regionally. Leaf-footed bug refers to leaf-like expansions on the legs of some species, generally on the hind tibiae. In North America, the pest status of species such as Anasa tristis on squash plants and other cucurbits gave rise to the name squash bugs.
