On their primary host (elder), Aphis sambuci apterae are very variable in colour from dark green through to yellowish brown; on their secondary host (e.g. root collar of dock) Aphis sambuci are usually dark green. Adults and immatures often have white waxy stripes across the sides of the abdominal segments. Antennae, siphunculi and legs blackish on the primary host and brownish in root colonies. The dorsal abdominal sclerotic pattern comprises small marginal and postsiphuncular sclerites, dark intersegmental muscle sclerites and variably complete transverse bands across tergites 6-8. Tergites 1-4 and and 7 have marginal tubercles (visible if you expand the images below) between their dark marginal sclerites. The cauda is dark and bluntly tapering. The body length of adult Aphis sambuci apterae is 2.0-3.5 mm.
