The generic position of this species is a bit unstable. Hippophae 

 and Elaeagnus serve as its winter hosts and Lamium, Polygonum 

 and Stachys share the summer honors. For a critical review with 

 figures see Gillette (1915a). 



M. persicae (Sulzer). Aphis persicae Sulzer, Aphis dianthi 

 Kaltenbach. Sometimes Rhopalosiphum. 



Abg. Ges. Ins., 105, 1776. 



This species has a range of food plants wide enough to entitle 

 it to the term "general feeder." The figures published by Gillette 

 (1908a) are excellent.
