According to Müller (1873/1883) in Germany, the flowers of True Forget-Me-Not attract small butterflies and dance flies (Empis spp.); these insects feed on the nectar. Two polyphagous aphids, Myzus persicae and Rhopalosiphum padi, have been observed to suck plant juices from Myosotis spp. (Forget-Me-Not species) in Illinois (Hottes & Frison, 1931). When this wildflower forms colonies of plants along wetlands, it provides cover for snakes and small animals.
