Cryptamorpha desjardinsii

Distinguished from similar silvanid beetles by the regular black markings on the elytra combined with its small size (4–5 mm). Within its expanded range, it may be confused with other Cryptamorpha species or small silvanids; examination of elytral pattern and body proportions is necessary for reliable identification.

A small beetle measuring 4–5 mm in length. The elytra bear regular black markings.

Associated with plants supporting fungal growth, particularly where mildews and moulds occur. In its introduced range, it occupies similar conditions to its native tropical Asian habitats.

Native to tropical Asia; now cosmopolitan through introduction. Established in Europe, North America, the Caribbean, and Oceania including Australia and New Zealand. Introduced to New Zealand via Australia.

Feeds on mildews and moulds found on plants. Commonly observed on flax.

Introduced to multiple regions outside its native range, with documented spread to New Zealand via Australia. No documented economic or health significance.
