The Vancouver Aquarium's Graham Amazon Gallery is now home to thousands of tropical butterfly species.

Among the variety of butterflies on display, keen-eyed visitors can see the colourful blue morphos, heliconians and giant owl butterflies.

"People will see a wide variety of butterflies flying in our gallery. You'll see them feeding on different forms of nectar and fruit as well as native South American flowers," says assistant curator Andrea Cotter.

All of the butterflies come from a butterfly farm in Costa Rica, and arrive as pupae that visitors can view on display.

The public can watch the transformation from pupae into colourful butterflies.

The gallery hasn't had butterflies in the gallery since 2014. Due to positive feed back feedback from its members, the aquarium has brought them back -- but only until the end of September.
