Diet and Behavior
Diet: coll'ed from Quercus havardii and Q. vaseyana (Fagaceae) in "central TX" and blackberry ( Rubus , Rosaceae) in LA ( 5 ) , but the range of those two oaks are on the western edge of the beetle's range, so the primary host(s) is likely one or more other oaks.

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