Coccotrypes
Coccotrypes is a genus of bark beetles (Curculionidae: Scolytinae) comprising approximately 130 described species. The genus is notable for its specialized seed-boring habits, with several species developing entirely within seeds or propagules of host plants. Coccotrypes dactyliperda (date stone beetle) and C. rhizophorae are economically significant pests of date palms and mangroves respectively, having achieved cosmopolitan distributions through human-mediated dispersal of host plant material.
Coprophilus
Coprophilus is a genus of rove beetles (Staphylinidae: Oxytelinae) containing approximately 30–32 species. Members are restricted to temperate regions of the Northern Hemisphere and lead cryptic lifestyles in decomposing organic matter. The genus name derives from Greek roots meaning 'dung-loving', reflecting their frequent association with herbivore dung and decaying plant material. Species identification is complicated by high morphological variability and underdeveloped systematics.
Cremastocheilus castaneae
anteater scarab beetle
Cremastocheilus castaneae is a myrmecophilous scarab beetle known as an 'anteater scarab' for its specialized predatory relationship with ants. Adults and larvae inhabit ant colonies, primarily those of mound-building Formica species, where they feed on ant brood. The species exhibits remarkable morphological and behavioral adaptations for colony infiltration and survival, including death-feigning behavior to gain entry and dense, armored exoskeletons for protection. It is one of approximately 35 North American species in the genus Cremastocheilus, which reaches greatest diversity in the desert southwest but occurs across much of the United States and southern Canada.
Cremastocheilus harrisii
Eastern Ant-loving Scarab
Cremastocheilus harrisii is a species of anteater scarab beetle in the family Scarabaeidae. As a member of the genus Cremastocheilus, it exhibits the specialized myrmecophilous lifestyle characteristic of this group, living within ant colonies and feeding on ant brood. The species is part of a genus of approximately 35 North American species that have evolved remarkable morphological and behavioral adaptations for surviving in hostile ant nest environments.
Cremastocheilus spinifer
anteater scarab beetle
Cremastocheilus spinifer is a myrmecophilous scarab beetle species that lives within ant colonies as a predator of ant brood. Like other members of its genus, it exhibits remarkable behavioral and morphological adaptations for infiltrating and surviving in hostile ant nest environments. The species is part of a group of approximately 35 North American species known as "anteater scarabs" for their specialized diet of ant larvae and pupae.
Strumigenys
Mustache and Pygmy Snapping Ants
Strumigenys is a hyperdiverse genus of small predatory ants in the subfamily Myrmicinae, comprising over 880 species. Members are characterized by specialized mandible morphology ranging from gripping to trap-jaw mechanisms, and cryptic lifestyles primarily in leaf litter and soil habitats. The genus exhibits remarkable diversity in nesting strategies, including solitary nesting, xenobiosis, and social parasitism. Several species reproduce via thelytokous parthenogenesis, a rare trait among ants that facilitates colonization of new environments.
