2005 Windsor Butterfly Count

Butterfly counts are carried out in a similar fashion to Christmas Bird Counts using a count circle fifteen miles (24 km) in diameter. Counts are sponsored by the North American Butterfly Association (NABA). Windsor's count circle includes Windsor, LaSalle, the lower portion of the Canard River, McGregor, Maidstone and Tecumseh. Field observers pay a small fee to participate and attempt to identify and count every individual butterfly encountered. Garden watchers, backyard observers and children under 12 can take part for free.

Join us for the 2006 count on Saturday, July 8.



In 2005 twenty-two participants found 2,312 butterflies of 54 species. The Ojibway Prairie Complex received the majority of coverage. Sites visited by counters included Spring Garden Natural Area, Tallgrass Prairie Heritage Park, Ojibway Park, Ojibway Prairie Provincial Nature Reserve and several sites in LaSalle. The count was hosted by the Ojibway Nature Centre and The Friends of Ojibway Prairie sponsored a picnic lunch and refreshments.

Butterfly numbers were much improved from the poor count last summer although Monarch numbers remained low. It was only the second count for Dreamy Dusky Wing and 'Northern' Oak Hairstreak was recorded for count week. New high counts were set for Red-spotted Purple, Crossline Skipper, Little Glassy Wing and Delaware Skipper while Little Yellow and Summer Azure tied previous high counts. The count recorded an excellent variety of hairstreaks (6 species) and skippers (21 species). 67 species (plus 1 count period) have been recorded over the past twelve butterfly counts.
