Acmon Blue – Plebejus (Icaricia) acmon
This little butterfly is fairly common, and more widespread than some of the other ‘Gossamer Wings’ (Lycaenidae); the Acmon Blue has a much longer flight period than many other ‘blues’ and it visits gardens, and can be seen in open fields, and even along roadsides.
Basically, as with so many butterfly species; the butterflies are where their host plants are! The Amon Blue larvae usually feed on plants in the Pea (Fabaceae) family, but also on some plants within the Knotweed (Polygonaceae) family, primarily various native Buckwheats. The Acmon Blue, which often produces multiple generations each year feeds interchangeably on plants in these two families; giving scientists a hint that there must be a chemical commonality between the two plant families.
