by the similarity of Needham's and Golden-winged. I'd have guessed Golden due to the yellow anterior wing veins and the orange stigma, though I know there are other indicators. Would you please educate me on why it's Needham's? Thank you.

Yes, they are confusing. On your bug, the right forewing shows the vein color the best. Before the nodus, the costal vein is slightly darker than after, where it appears to turn orange. There is orange color on the vein immediately behind the costa at the base of the wing, and the orange comes up the nodus and follows the costa thereafter. On Golden-winged, the costa is usually more uniformly orange for the entire length. The yellow coloration on the side of your bug's thorax also appears to project forward towards the collar. On Golden-winged the yellow color stops short of the shoulder area.

As an editor, I am able to view this image full size, where these details are much easier to see. I probably wouldn't have been able to do it just viewing the smaller image.

This is extremely helpful.
