With hundreds of full-colour photographs, this new publication shares the local history of butterflies and details on where they live in Toronto. It is part of a Biodiversity Series being produced by the City to commemorate the Year of Biodiversity 2010. Other booklets in the works include Spiders, Trees and Shrubs, Mammals, Fishes, and Reptiles and Amphibians. You may remember Birds of Toronto (2009) — it is hoped that it will be reprinted. Whether you are a butterfly enthusiast, a nature nut, or just interested in learning more about your city, don’t miss this book. You can pick up a free copy at your local Toronto Public Library branch while they last.
