The male has a pair of stout, forward pointing horns Beetles always make the entrances through the top of the sporocarp, whether they are living in Ganoderma applanatum in the northern part of their range or in G. lucidum in the southern part... Those living in the north are generally of a lighter color than those in the south, which tend to be black rather than cocoa brown. (Comment here ) Feign death when disturbed and live more than two years in nature ( 5 ) When attacked they play dead or release noxious, irritating fluids from abdominal glands. The potency of these are determined by the fungus they eat. ( 6 ) The variation of the horn and body size is determined by the quality and quantity of food consumed in the larval stage. Its the mothers choice of egg-laying sites that selects horn and body size. ( 6 )

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Bolitotherus cornutus. 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.
