Member of Family: Lycaenidae

French common name: Azur nordique

This species is also known as the "Northern Spring Azure" and "Lucia Azure". It should be noted that this species can be extremely variable. Though there are 3 recognized variant forms or "morphs" shown above, intermediate forms are often seen. This species can be difficult to distinguish from the other closely related Celastrina species based solely on appearance ( especially in photographs ). It is the most common species in Quebec, and the only species found in the North. It is now believed to have a second flight in summer in Southern Quebec, creating confusion with the Summer Azure (which may be found in Southern Quebec near the US border).

There is still uncertainty about the taxonomy of the genus Celastrina in Eastern Canada, and experts are not in agreement on where to draw the boundaries between species. Some more recent research is referenced at this link: Ontario Insects page on Azures

For further info on this species, refer to the Butterflies of Canada ( en français )

(Note: Although the Butterflies of Canada describes Celastrina ladon, much of that description actually applies to the Celastrina lucia. Since the publishing of The Butterflies of Canada, the two species were determined to be distinct, and C. lucia is the more common species in Quebec. )
