Pidonia densicollis
(Casey, 1914)
Pidonia densicollis is a of flower longhorn beetle ( Lepturinae) in the Cerambycidae. It is distributed in the United States. The species was described by Casey in 1914. As a member of the Rhagiini tribe, it likely shares the flower-visiting habits common to many lepturines, though specific behavioral observations for this species are limited.

Identification
Members of the Pidonia are small to medium-sized lepturine beetles, often with black and yellow or reddish color patterns. Pidonia densicollis can be distinguished from by its relatively dense pronotal punctation (referenced in the specific epithet 'densicollis,' meaning 'dense-necked'). Accurate identification to level typically requires examination of detailed morphological characters including antennal proportions, elytral coloration patterns, and male genitalia.
Distribution
United States.
Similar Taxa
- Other Pidonia speciesMany Pidonia share similar small size and black-and-yellow coloration patterns. P. densicollis is distinguished by its denser pronotal punctation, but precise identification requires careful morphological comparison.
- Other Rhagiini genera (e.g., Anthophylax, Brachyta)These small lepturines can appear superficially similar in size and flower-visiting . Distinguishing features include antennal structure, pronotal shape, and detailed elytral .

Taxonomic note
The specific epithet 'densicollis' refers to the dense punctation of the pronotum (the 'neck' region of the ), a diagnostic character for this .
Field observation context
A collector in northern Arizona observed small black/yellow 'Pidonia?' beetles on flowers of Hymenopappus filifolius and Sphaeralcea ambigua in early June, at approximately 7000 ft elevation in a ponderosa pine/Gambel oak transition zone. These observations suggest the may be active in late spring to early summer in montane , though positive identification was not confirmed.
