All of the specimens that I have seen from central and eastern Mayland are bright silvery blue. Dr. John Glaser (Addenda to the Checklist of Maryland Cerambycidae, Maryland Entomologist, Volume 3, Number 4, March 1992) reported that in Maryland, all beetles east of Dans Mountain in Allegany County are blue whereas all the specimens to the west (Garrett and far western Allegany Counties) are purple.
