I wasn't sure about this little butterfly so sent a pic into a butterfly website for verification. It's one of the little grass-skipper clan and was introduced into Canada in the early 1900's. I find it drinking nectar from smaller flowers like this birds-foot trefoil. I have been seeing lots of these little guys for weeks. The butterfly website verified my assumptions. It noted a large number of recent sightings and stated that they will be abundant this year. They only have one hatching a year so I'll probably stop seeing them by August. Maybe not as big as most butterflies but definately among the prettiest.
