Lacon nobilis
Lacon nobilis is a of click beetle in the Elateridae, placed in the Agrypninae. The Lacon comprises numerous species distributed primarily across the Palearctic and Oriental regions, though specific information about L. nobilis remains limited in publicly available sources. As with other elaterid beetles, possess the characteristic clicking mechanism formed by the prosternal process and mesosternal receptacle that enables their signature escape response.

Identification
Members of the Lacon can be distinguished from other click beetle genera by their elongate body form, (thread-like) , and the structure of the pronotum which typically lacks pronounced lateral carinae. Specific diagnostic features for L. nobilis versus are not documented in readily accessible literature. are likely moderate to large in size for the , with the robust build typical of Agrypninae.

Behavior
As with other click beetles, L. nobilis presumably exhibits the 's characteristic escape mechanism: when threatened, the arches its body, then rapidly straightens it, causing the prosternal spine to strike the mesosternal groove and produce an audible click that can propel the insect into the air. This has been observed across Elateridae but has not been specifically documented for this .

Taxonomic Note
The Lacon is taxonomically complex and has undergone repeated revision. Many were formerly placed in the genus Agrypnus, and species-level identification often requires examination of male genitalia. The iNaturalist platform records only four observations of L. nobilis, suggesting either genuine rarity or under-recording due to identification challenges.
Data Limitations
No published biological studies, descriptions, or ecological accounts specifically addressing L. nobilis were identified in the provided source material. The species epithet 'nobilis' (Latin for 'noble') has been applied to multiple unrelated across zoology, including Coregonus nobilis (a whitefish) and Steatoda nobilis (a spider), but these share only a name with L. nobilis.
