Diet and Behavior
Diet: The primary host is Baccharis pilularis . Palmer (1986) noted that although T. flavolimbata has been reported [e.g. in Tilden(1951)] on a number of other possible hosts, such as Aster, Solidago, Artemesia, Senecio and Eriodictyon [...], feeding was not clearly verified & documented and the associations may have been simply incidental or based on misidentifications. However, T. flavolimbata has been photographed feeding on B. douglasii , and seen and collected on Aster chilensis

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