Acanthocephala terminalis is usually around 18–25 millimetres (0.71–0.98 in) long [1] with a dark gray to black color. The fourth (and last) segment of their antennae have orange coloration, and the tibia of their hind legs have a flat, leaf-like, appearance. [1]
Acanthocephala, also known as spine-headed bugs, [2] [3] is a New World genus of true bugs in the family Coreidae. [1] The scientific name is derived from the Greek ἄκανθα (akantha) meaning "thorn/spine" and κεφαλή (kephale) meaning "head". [4] This name refers to the diagnostic spine on the front of the head.

Acanthocephala / ə ˌ k æ n θ oʊ ˈ s ɛ f ə l ə / [3] (Greek ἄκανθος, akanthos 'thorn' + κεφαλή, kephale 'head') is a group of parasitic worms known as acanthocephalans, thorny-headed worms, or spiny-headed worms, characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host.
Acanthocephaliasis is a human disease caused by parasitic worms in the phylum Acanthocephala. They rarely infect humans. They rarely infect humans. The worms' typical definitive hosts are racoons, rats, and swine, but it can survive in humans.
(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.
Life cycle of Acanthocephala. [3] [a] The life cycle of an acanthocephalan consists of three stages beginning when an infective acanthor (development of an egg) is released from the intestines of the definitive host and then ingested by an arthropod, the intermediate host. Although the intermediate hosts of Acanthocephaloides are arthropods.
Archiacanthocephala is a class within the phylum of Acanthocephala. [2] They are parasitic worms that attach themselves to the intestinal wall of terrestrial vertebrates, including humans. They are characterised by the body wall and the lemnisci (which are a bundle of sensory nerve fibers), which have nuclei that divide without spindle ...
