Butterfly Report 1 May to 15 May 2011

John Poland sends us an updated butterfly report:

The first half of May is the time to see Whites and Elfins. All four Elfins on the KFN list have now been sighted at various locations mostly on the Canadian shield. The highlight was finding the rare Brown Elfin both at the Second Depot Lakes Conservation area and at Menzel Centennial Provincial Park. The four white butterflies on the KFN list are now also present. These include the West Virginia White and the Olympia Marble which we are lucky to have in our area. Of these eight butterflies only the Eastern Pine Elfin, the Mustard White and Cabbage White will not be around for much longer so get looking.
There have been reports of quite a number of new arrivals since the last update. They include Clouded Sulphur, Juvenals Duskywing, Columbine Duskywing, Black Swallowtail, Red Admiral and Northern Crescent and most recently the Eastern Tailed Blue and Silvery Blue. The other highlight to report is the return of the Chryxus Arctic to Rock Dunder. These Arctics were re-discovered last year and I am happy to report that they are back in good numbers.  
The three rare butterflies that I will be looking for in the last two weeks of May are all Hairstreaks. They are the Gray (four were sighted last year but they often go unreported), the Juniper (only one sighted at Menzel last year but quite a number seen in our area in 2008 and 2009) and the Early (last reported in our area at Helen Quilliam Sanctuary in 1979 but are likely present high in beech trees).
