Anacaena globulus
This record describes Anacaena globulus (species). Recorded family: Hydrophilidae. Recorded order: Coleoptera.
Identification and Appearance
2.5 to 3.5mm. Strongly convex above, shape broadly oval and colouration dark, almost black with contrasting pale pronotal and elytral margins. Distinguished from our other species by the form of the mesosternum; the sharply-declined part in front of the coxae is at most slightly raised medially but lacks any transverse or longitudinal keels. High quality photos showing key features required. All year, but mainly encountered from mid-April to November. No additional images available for this species.

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