SeasonalityAdults of this species has been collected in May to September.
IdentificationMember of the inaequale group (subgenus Bracteon). Similar to B. inaequale in color though usually with more sombre ground color (sometimes green); smooth parts of elytra purple or cupreous, as a rule; prothorax sometimes with darker disc; femora more or less reddish at base but tibiae hardly paler. Prothorax broader than in B. inaequale. It is best distinguished from this species on the sculpture of elytra; these are strongly transversely depressed behind the base and only intervals (2-) 3-5 are shiny in front of the depression; the mirror of the 7th (-8th) interval behind middle is never isolated but broadly connected with the similarly sculptured inner intervals. Length 5.4 to 6.3 mm.
