The pink #tansyaphid #Metopeurum #fuscoviride is native to Europe and prefers forming large #colonies on #tansy #Tanacetum #vulgare.This aphid is very attractive for #ants, as one aphid has a high #honeydew #production with in average 1 milligram of honeydew per hour. Authors M. K. Fischer et al. (2002) found the #aminoacid #concentration in honeydew increasing with #aphid age.

#Blueweed #Echium #vulgare (#Boraginaceae) is naturally distributed from #Europe to Central Asia and occurs as a neophyte e.g. in North America and Australia. It is highly #adapted to #drought and nutrient-poor soils. According to K. A. Leiss et al. (2004), the amount of #nectar #produced is genetically determined, although #environmentalfactors also play a role. #biodiversity
