Please note that Section 3 in each ofthese publications addresses the corrections required to previous T.E.A. Occasional Publications. 1 Section 6 ofthis publication is organised in accordance with "A Catalogue/Check-list ofthe Butterflies of North America North ofMexico" by Lee D. Miller and F.M. Brown (Lepidopterists' Society Memoir No. 2 - 1981) as corrected by "Supplem~nt to A Catalogue/Checklist of the Butterflies of North America North of Mexico" by Clifford D. Ferris, Editor (Lepidopterists' Society Memoir No.3 - 1989). The compiler has also noted, where of interest, the usage of James A. Scott in his "The Butterflies ofNorth America" (1986). The common names are as per Alexander B. Klots - "A Field Guide to the Butterflies ofNorth America, East ofthe Great Plains", except in a few cases not included in Klots. For the Moths, "Check List ofthe Lepidoptera ofAmerica North ofMexico (1983)" by Ronald W. Hodges et al. is used. The contents of this publication have been checked for errors and accuracy as much as possible. Any errors and omissions will be corrected in future publications. Each locality listed herein is followed by a number in square brackets. This number is the County, District or Regional Municipality as shown in Figures 1 & 2, e.g. Hearst [53] means Hearst (Cochrane District).

These changes will affect previous records up to and including "The Ontario Butterfly Atlas" (Holmes, Hess, Hanks and Tasker, 1992), and numbers from those records should be noted in any citation with the necessary emendations. Where the date given is followed by a number in brackets, this represents the number of specimens encountered, i.e. (3). Also note that M = male, F = female, C = collected, R = released and S = sighting. Ifthere are any errors and/or omissions or suggestions please advise: Alan 1.

It did not seem to be a good year for Lepidopterists! March - Winter continued with cold temperatures dominating and it was the coldest March in eight years. It was also dry throughout the north and in areas west of Lake Ontario to London. But extreme southeastern and south-western Ontario were slightly wetter than normal. April - This was a wet, stormy, cold and sunless month. Province-wide temperatures were 1 to 2 C colder than normal and it was the coldest April since 1989 at most locations. At Sault Ste. Marie it was the coldest April since 1978 while both Thunder Bay and Hamilton were the coldest since 1982. Precipitation was heavy over Ontario except for a region east of Georgian bay north to Temiskaming including the Ottawa valley. It was the wettest April ever recorded at St. Catherines. May - Generally it was a pleasant sunny month with near normal temperatures and close to normal precipitation. However, very warm and record cold was mixed in. The final 10 days ofthe month seemed more to herald winter than approaching summer. Seven cm of snow fell in Sudbury where it was the coldest May since 1961. June - This was a cold month averaging 2 deg. colder than normal province-wide. In the London Windsor area it was the coldest June since 1980 and in Moosonee the coldest since 1978. On the morning ofJune 22nd the province was hit by a very late ground frost with damage to plants in areas as far south as Woodstock. The cool temperatures were accompanied by dry weather across most of Ontario except the extreme Northwest. For Petawawa this was the driest June ever recorded. July - This was the coldest July in Toronto in 102 years. It was also wet; London had the wettest July since 1932. It was also cloudy and sunshine was reduced 100 hours over normal, so it was the cloudiest July on record. Temperatures were 2 to 4 degrees below average everywhere in the province. Ontario did not reach an afternoon high of30 C or more during the whole month, which has never happened before. August - This was a cool, wet month. The whole June to August period was the coolest since 1927. Temperatures averaged 1 to 2 degrees below normal in the north and 2 to 3 degrees below average in the south. London, Hamilton and Sarnia endured generally the coldest August on record. However, the final week of August had hot, hazy weather over most of the province. Rainfall was again abundant across Ontario with 159 mm at Timmins leading the way. Most localities had 100 to 155 mm ofrain compared to the average 70 to 90 mm. August was also cloudier than normal. September - This month did not compensate for Ontario's most miserable summer of the century. However, near normal temperatures and sunshine provided a small consolation.
