What is known about the Diadem Roundleaf Bat?
The diadem roundleaf bat belongs to Hipposideridae, not Rhinolophidae; nose shape matters, but a single photograph may not settle identification.
Read that fact alongside the scientific name and species source, not as proof from an unclear photograph. Populations, ages and taxonomic limits can differ; when identification is uncertain, record the broader group.

How can you observe the Diadem Roundleaf Bat?
Watch from a distance, do not feed, and avoid sharing precise locations of vulnerable dens or resting sites. Do not try to catch or touch wild mammals. A well-documented sighting helps others check the identification without turning one encounter into a conservation-status claim.
