R Emmitt Clay, 2002-05-24. ID comments by John Petranka: "teneral/very immature male Amber-winged Spreadwing that has not yet developed its adult coloration (i.e. is female-like in body color; the wings may not yet be very amber or their amber color may not show well on this background). Note the pattern of dark markings on the thorax. The dark border in Swamp Spreadwings is straight or very slightly undulating. In this individual the border is jagged with 2-3 tooth-like antero-ventrally pointing projections. Also on the thorax note the 2 ventro-lateral dark patches, the rear-most of which comes up to meet the pleural suture and the more anterior of which touches the middle projection."
