How to Identify?
There are similar species with the intense blue color of the wing, endemic to the region. I identify this species based on the pattern of black and orange spots on the underside of the wings.
We combine physical characterics and behavior patterns with location and seasonal aspects to identify species.
Where & When to Spot?
I have been able to spot this species in different parks in Montreal. Usually late summer, early autumn.
With each photo, we store date and geo-location providing us data about location and season of observation. We also use a tracking utility to save observations in the field when there was no opportunity to take a good shot.
