Myzocallis castaneae
I have Aphids of Western North America North of Mexico, and there is an image of an alate Myzocallis castaneae that looks like a good fit with those black legs and black antennae. Also fits the description in Aphids on the World's Plants:

Myzocallis (Castaneomyzocallis) castaneae (Fitch) Alatae are yellow with black ANT III-VI, tibiae and tarsi. The forewing has the pterostigma with a black spot at its base and a line of pigment following its posterior margin, and vein Cu1b and base of Cu1a are black-bordered. BL 2.1-2.6 mm. On undersides of leaves of Castanea dentata and Castanea sp(p). in North America (Quednau & Remaudière 1987). Monoecious holocyclic; sexuales occur in October in California (Essig 1917).
