- Phloeodes plicatus(Wrinkled Ironclad Beetle)
Phloeodes is a of ironclad beetles in the Zopheridae, native to western North America. The genus includes the well-known Phloeodes diabolicus, commonly called the diabolical ironclad beetle, which has attracted scientific attention for its exceptional mechanical durability. Members of this genus are flightless, have heavily sclerotized , and feed on fungi growing under tree bark. The genus has been synonymized with Nosoderma in some taxonomic treatments, though Phloeodes remains in widespread use.

Identification
Flightless beetles with extremely hard, heavily armored . The are densely layered and interlock with the exoskeleton to form a protective shell. Body form is dorsoventrally flattened and low to the ground. Distinguished from other zopherid beetles by the combination of the diabolical ironclad beetle's extreme structural durability and the specific elytral architecture with internal layers and tight joints.
Images
Habitat
Found under tree bark in forested environments, particularly in the Sierra Nevada foothills and desert regions of western North America. Associated with fungal growth on decaying wood.
Distribution
Western North America, including desert regions and the central Sierra Nevada foothills of California. Documented from Calaveras County, California (Murphys area) and surrounding regions.
Diet
Mycophagous; feeds on fungi growing under tree bark.
Behavior
Remains flat and low to the substrate. Can survive extreme compressive forces due to structural adaptations of the .
Ecological Role
Decomposer; contributes to nutrient cycling through consumption of fungi associated with decaying wood.
Human Relevance
Subject of biomechanical research due to exceptional exoskeletal durability. The structural design has inspired engineering applications for strong fasteners with potential use in vehicles, bicycles, and aircraft. Commonly displayed in museum educational programs.
