Uroleucon sonchi
Here are the steps through the key to get to U. sonchi

http://www.aphidsonworldsplants.info/C_HOSTS_Seq_Sop.htm#Sonchus

1. Hind tarsus II of normal length, 6
6. Has the polygonal reticulation, 7.
7. Dark siphunculi, 9.
9. Cauda much paler than siphunculi, 11
11. Antenna III /(Antenna IV + V)= 0.7, 13.
13. R IV+V / HT II = 0.8, most hairs not on scleroites, coxa dark. Solid match for U. sonchi.
