Onagraceae, monophagous

Oenothera biennis, brevihypanthialis, casimiri, deflexa, flaemingina, hazeliae var. subterminalis, lamarckiana, oakesiana, pseudosuaveolens.

notes

This is the only aphid that is fully dependent on evening primrose. The species very closely resembles Aphis oenotherae Oestlund, 1997, and was confused with it until recently. A. oenotherae has Ribes as primary host plant, and migrates to Onagraceae in summer; A. holoenotherae lives permanently on Oenothera. For the moment oenotherae seems not to occur in Europe.
