Macrosiphum albifrons

Wink, M. and Romer, P. 1986. Acquired toxicity the advantages of specializing on alkaloid-rich lupins to Macrosiphum albifrons (Aphidae). Naturwissenschaften, 73 210-212. 

Besides avoiding, some insects can tolerate the defense chenustry of their host. The potato beetle Leptinotarsa decemlineata) lives on Solanum species containing steroidal alkaloids, which are tolerated but not stored by this species. The bruchid beetle, Bruchidius villosus, predates seeds of QA rich plants, such as Laburnum anagyroides. This beetle eliminates most of the dietary cystisine with the faces. Certain aphids can store the dietary alkaloids, for example, QA in Aphis cytisorum, A. genistae, and Macrosiphum albifrons and PA in Aphis jacobaeae and A. cacaliaster [70].
