The butterflies we call painted ladies at home are called “belle-dames” here–beautiful ladies. They’re migratory and occur all over the world. This sign in the Les Jardins Gamelin is in the middle of several garden beds planted with butterfly host plants and flowers. In their midst, there’s a geodesic “butterfly house” and exhibit (you can see a little bit of the dome in the background).

It says:
The Butterfly House
The painted ladies cross all of Canada and the United States each year during their migration. For this important pollinator of our ecosystems, we have created a house and a reproduction space: the butterfly house. A selection of plants necessary for their development were chosen in order to create this mini butterfly farm.
I’ll get more photos of the actual garden next week when we go to Jardins Gamelin for the free circus shows that happen there every summer.
