Butterfly Count; TEA = members field trip; HRCA = Halton Region Conservation Authority The basis for selection ofthe data included in this publication was as follows: a) New information on range and new occurrence localities; b) Valuable data on flight period, broods and . population monitoring, and c) Life history data including foodplants, nectar sources, larval description and habits, ovipositing data and behaviour, pupal description and siting, adult habits, predation, etc. Occasional Publication #'s 10 through 28 are designed to complement each other in such a way as to present in a common format all the information (as selected) known to the compiler with respect to Ontario Lepidoptera to the end of 1995. Please note that Section 3 in each ofthese publications addresses the corrections required to previous TE.A. Occasional Publications. 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 "Supplement 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). In addition, recent information on a number of species has necessitated some changes or additions to the nomenclature. These are noted in the listings. 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 of the 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). Note: Changes which have occurred in the county names or county amalgamations were incorporated into publication # 25-93 (1992 Summary). These changes will have affected 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 J. Hanks, 34 Seaton Drive, Aurora, Ontario L4G 2Kl - (905) 727-6993 Back issues ofsome TE.A. publications and memberships are available from the Treasurer ofthe TE.A., Alan J.

The above-average annual temperature is a result of seasonal means that were considerably above-average through the winter (+1.7 Celsius degrees), spring (+1.1 degrees) and summer (+0.8 degree); and close to average for the autumn (+0.1 degree). Across Canada, as elsewhere in the hemisphere, 1995 was a year riddled with climatic extremes including excessive summer heat and humidity in central and eastern regions; and record December cold and heavy snowfalls at many locations across the country. In spite ofthese wild climatic fluctuations, 1995 ranked as only the 14th warmest for Canada since national temperature records began in 1895.
