Tragidion gracilipes
Linsley, 1940
Tragidion gracilipes is a of longhorn beetle in the Cerambycidae, described by Linsley in 1940. The Tragidion comprises eleven recognized species distributed across North America and Mexico, characterized by bright orange and black coloration that mimics spider wasps (Pompilidae) in the genera Pepsis and Hemipepsis. Species of Tragidion have historically been difficult to identify due to morphological similarity, geographic variation, , and potential hybridization. A comprehensive taxonomic review by Swift and Ray (2008) clarified species boundaries within the genus, though T. gracilipes itself remains poorly documented in the literature.
