This record describes Ammodonus fossor (species). Recorded family: Tenebrionidae. Recorded order: Coleoptera.
Identification and Appearance

Ammodonus fossor (Ammodonus fossor) is a species in the family Tenebrionidae, commonly known as darkling beetles, belonging to the order Coleoptera (Beetles). It is classified within the subfamily Blaptinae, tribe Opatrini, suborder Polyphaga, superfamily Tenebrionoidea. This species belongs to the genus Ammodonus. As a member of class Insecta, phylum Arthropoda, it is part of the kingdom Animalia. Size: 4.5-5 mm. It is found in open sandy areas in disjunct populations separated by vast areas of forest; these micro-habitats are periodically lost due to plant succession and regained by natural fires or prescribed burns. Active during Mar-Sept.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Ammodonus fossor. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
