Appearance
Apterae are around 3.2-4.1mm in length and wax powdered green or pinkish-brown. The green version seems to be the more common variant. The alate females look much the same as the apterae, apart from carrying wings of course. Antennae, legs, siphunculi and cauda are all black.Distribution
This is basically a European species, but BugGuide carries some photos shot in Minnesota on the host plant, considered an invasive pest in the US.References:
