Location: Humber Bay Butterfly Habitat
Date photo taken: 23 July 2014
The Humber Bay Butterfly Habitat is a waterfront park just west of the Humber River. While it's a joy to walk through, the native species planted here were selected with butterflies and other pollinator species in mind, not humans. One of the most important species in the area is milkweed. It's important because Monarch butterflies lay their eggs on milkweed plants, and once the caterpillars hatch, they feed on the leaves. Milkweed leaves contain toxic compounds which the caterpillars store up, making them unpalatable to birds and other creatures that might otherwise consider them lunch.
The best time for spotting Monarch butterflies in Toronto is late August, and one of the best places to see them is Tommy Thompson park. The park is hosting a Butterfly Festival on August 23rd, with activities, nature hikes and educational displays. Hopefully, there will be a good turn out, but Monarch populations have been in steep decline in recent years. One cause is a decline in native species, many of which are considered weeds. To help out the struggling butterflies, the David Suzuki Foundation has launched their #gotmilkweed campaign to encourage Torontonians to plant milkweed and other butterfly-friendly plants in their gardens and in under-utilized public spaces like medians and hydro corridors.
