Thank you for joining us for the 22nd Annual Biology Butterfly Show

Saturday, October 2 – Sunday, October 10, 2021

Thank you for joining us this year! We hope to welcome you back to the greenhouses in-person in 2022.

The 2021 show has come to an end, but there’s more to discover!

Help support the butterflies!

The Butterfly Show has been free and open to the public since its creation 21 years ago, although we rely on your generous donations to keep it running year after year.

Donations can be made online using Carleton University’s secure FutureFunder platform.

Help Support Future Butterfly Shows


Meet the Butterfly Show Volunteers! Our show would not have been able to run for 22 years without them!

In 2020, Let’s Talk Science Ottawa produced 600 individual hands-on learning kits related to the Butterfly Show. These kits brought science-learning to indigenous children and children living in lower socio-economic areas during the week of October 5, 2020.

In 2021, Let’s Talk Science is connecting with more than 30 classrooms the week of October 4!
