[Note Guidelines] Photographer's Note
This rather tattered male was flying around and trying to nectar just before a huge rainstorm moved in. It was more concerned about it's stomach then the presence of the lens.

The upperside is a shiny light blue, with a dark grey border around both wings, wider in the female and sometimes suffusing the entire wing surface with grey. The underside is grey, with a single row of round, black, white-rimmed spots on both wings. Wingspan: 18 to 28 mm.

Glaucopsyche lygdamus is found over much of the U.S., extending farther south in the west. In Canada it occurs in every province and territory, but is absent, except for a few old records, from southwestern Ontario; Ancaster, west of Toronto, appears to be the present southern limit for subspecies couperi. Its range extends north to Kuujjuaq (Fort Chimo), Quebec, Churchill, Manitoba, and Coppermine, Nunavut and Tuktoyuktuk, Northwest Territories.

The Silvery Blue has quite a strong flight, and is usually seen visiting flowers or on the ground in damp areas. It is most commonly seen in open woodland, flowery meadows, and roadsides, sometimes in small waste areas in cities. In places it seems to be expanding its range along roads following the spread of non-native plants such as Cow Vetch.

In the south, the single generation flies from early May to early July. In Newfoundland and the north, the emergence period is extended and the season runs from mid-June to at least mid-August.
