Prairie grasslands, wetlands such as bogs or marshes, sand dunes and undisturbed forests are the most populated butterfly habitats. Butterflies are very sensitive to any changes to their habitats, such as temperature, moisture or landscapes. This sensitivity makes them excellent indicators of the ecological conditions of a given area. Nose Hill Park has greatest number of butterflies recorded of any natural area in Calgary. As of 1995, 55 species have been identified, including 32 species in a day! Most species reside in the park, though there are seasonal butterflies, and those that have been windblown from other environments. Those butterfly species that prefer prairie grassland, shrub, and aspen parkland are the most common in Nose Hill Park. This habitat tends to be more common though there are rare case of butterflies from other habitats being identified. The ideal time to view butterflies on Nose Hill is bright sunny days between April and September. For further reading on butterflies you might like to try the following books:
