Diet and Behavior
Life History
Overwinters as adults beneath soil and plant debris and in clumps of some species of weeds. Adults emerge early spring to feed on young weed hosts such as cocklebur, smartweed, and crabgrass as well as early-planted corn. The resulting larvae feed on corn roots. Adults begin emerging from the soil in mid-July, feed briefly then begin to seek overwintering sites. (Steffey 2002)

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