suture and outer margin brown to black, sometimes very broadly so; almost always with a strong central dark spot on each elytron MAQ, pers. obs.: the thick black sutural line apppears to be more consistant character than the elytral spots which is likely why Potts characterized the suture before mentioning the spots.

Diet and Behavior

Life History

The adults are injurious to fruit-producing plants and the grubs are minor pests of corn, wheat and oats. The winter is passed as an adult. Eggs are laid in the spring and soon hatch, producing larvae whose average time of development was found to be 83 days. The pupal stage lasts on an average 16 days. The adults transform in the fall and remain in their pupal cells until the following spring, thus completing a one-year life cycle. (Hayes 1918)

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Anomalacra binotata. 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.
