Ptomaphagus cavernicola
This record describes Ptomaphagus cavernicola (species). Recorded family: Leiodidae. Recorded order: Coleoptera.
Identification and Appearance

This is a fully-eyed and functionally-winged species known (w/ one SC exception) only from caves in a largely disrupted but crescentric dist. from Mex. to IA to FL. (Peck 1973) The lack of significant variation in the cave pop. may suggest that the dist. was achieved during and shortly after the Wisconsinan glacial, and that cave restriction occurred during the Recent. (Peck 1982)

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Ptomaphagus cavernicola. 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.
