Macrosiagon flavipennis
This record describes Macrosiagon flavipennis (species). Recorded family: Ripiphoridae. Recorded order: Coleoptera.
Identification and Appearance

If you compare it to M. dimidiata , you'll notice this species has an odd, fin or cup-shaped tubercle on the posterior of the pronotum that the other one lacks. This species also has something of a dimple or concavity to its forehead. The females of M. flavipennis tend to have red abdoma whereas those of M. dimidiata tend to be all black. --Zack Falin, 11.iii.2005 These characters are shown below:

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