Cibdelis blaschkei

Mannerheim

Cibdelis blaschkei is a North American darkling beetle in the Stenochiinae. The stages were first described in 2014, revealing distinctive defensive structures and saproxylic . The inhabits forested regions of California, where larvae develop in soft rotten dry wood of dead branches. Both larvae and pupae possess urogomphi—abdominal armature that can be raised and curved forward as antipredator defenses. The complete has been documented through rearing from pupae with associated larval .

Identification

Larvae distinguished by combination of size (25 mm), elongate-cylindrical pale body with light brown bands, and prominent urogomphi capable of being raised and curved forward. identity confirmed through rearing from pupae with associated larval . Differentiated from Glyptotus cribratus by specific morphological details of stages documented in Steiner (2014).

Habitat

Forested regions of California. Specifically inhabits soft rotten dry wood of dead branches on living trees or in sections recently fallen from them. Pupal constructed within oak wood.

Distribution

California, United States.

Life Cycle

Larvae develop within rotten wood and construct pupal in which they pupate. confirmed complete through rearing: emerge from pupae with associated larval retained in pupal cells.

Behavior

Antipredator defense: larvae and pupae possess urogomphi (abdominal armature) that can be actively raised and curved forward when threatened. This represents a documented defensive against .

Ecological Role

Saproxylic insect contributing to decomposition of dead wood in forest . Inhabits soft rotten dry wood, indicating role in late-stage wood decay processes.
