Caenocara oculatum
(Say, 1824)
Caenocara oculatum is a small in the Ptinidae, originally described by Thomas Say in 1824. The belongs to a commonly known as puffball beetles, referencing an apparent ecological association with puffball fungi. It occurs in eastern North America with documented records from Nova Scotia, Ontario, and Prince Edward Island in Canada. The species remains poorly known biologically, with limited observational data available.

Identification
The Caenocara can be distinguished from other Ptinidae by its compact, somewhat rounded body form and antennal structure. -level identification within Caenocara requires examination of subtle characters including pronotal shape, elytral striation patterns, and male genitalia. C. oculatum specifically may be recognized by the presence of distinct ocellate or -like markings on the pronotum, as suggested by its specific epithet, though this requires verification against type material.
Habitat
Associated with fungal , particularly puffball fungi (Lycoperdaceae), based on -level . Specific microhabitat requirements for C. oculatum are not documented.
Distribution
Eastern North America. Documented from Nova Scotia, Ontario, and Prince Edward Island, Canada. The full range likely extends into the northeastern United States given the historical collecting locality patterns of Thomas Say.
Diet
Larvae have been observed feeding on puffball fungi (Lycoperdaceae) based on -level records; specific dietary habits of C. oculatum are not independently documented.
Host Associations
- Lycoperdaceae - larval food source-level association; specific records for C. oculatum not confirmed
Ecological Role
As a fungivore, contributes to decomposition of puffball fungi and nutrient cycling in forest . The -level role is inferred; specific ecological function of C. oculatum is not documented.

Taxonomic Note
placement has varied historically between Anobiidae and Ptinidae; currently accepted in Ptinidae following recent phylogenetic treatments. The epithet 'oculatum' refers to -like pronotal markings, a characteristic feature of this .
Data Limitations
Only 7 observations recorded in iNaturalist as of data compilation; biological information largely inferred from -level studies. Direct field observations and studies specifically targeting C. oculatum are lacking in published literature.
