Explanation of Names
Calleida decora (Fabricius 1801)
Adult head black, pronotum orange, elytra green with punctate striations; head and pronotum narrower than body; antennae filiform, twice as long as head, basal third pale - distal portion black, short hairs at base of each segment; "knee joints" blackish and remainder of femur and tibia yellowish-orange on all legs

The key below [slightly modified from(1) by Peter W. Messer 5.vii.2010] is for separating the similarly colored C. punctata and C. decora which usually cannot be distinguished without microscopic examination. See background discussion of the need for accurate species identification.
Head densely punctate with short pubescence. Eyes small and flat, horizontal diameter not exceeding length of temples (head behind eyes). Elytra very shiny, microsculpture obsolete. Tarsi convex dorsally, not furrowed. Internal sac of penis without flagellum. Colored as C. decora. Range: eastern half of North America but questionably into southern coastal states. 7.0–8.5 mm. ==> C. punctata LeConte
Head glabrous (except for normal supra-orbital setae). Eyes large and prominent, their diameter much longer than temples. Elytra luster dull from strong, regularly isodiametric microsculpture. Tarsi dorsally flattish with longitudinal furrow. Penis with long flagellum coiled into the basal bulb when in repose. Colored as C. punctata. Range: securely in the southeastern States, questionably into the midwestern States. 7–9 mm. ==> C. decora (Fabricius)
