WGL William G. Lamond Brantford Note: PP = Provincial Park; CA = Conservation Area; HRCA = Halton Region Conservation Authority I 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 33 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 2000. Please note that Section 3 in each of these publications addresses the corrections required to previous T.E.A. Occasional Publications. Section 6 ofthis publication is organized in accordance with "A Catalogue/Check-list ofthe Butterflies ofNorth 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 ofthe Butterflies ofNorth 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 in "Butterflies of Canada" by Ross Layberry, Peter Hall and Donald Lafontaine (1998) 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 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). Note: Ross Layberry of Ottawa has pointed out that the changes to county names that were made in publication # 25-93 (1992 Summary) and later created difficulty with records in his area since Leeds! Grenville and Stormont/Dundas!Glengarry are large areas which do not allow proper placement of the records. Accordingly, in this publication, the aforementioned counties will be represented with their original numbering, namely Leeds [27], Grenville [28], Stormont [29], Dundas [30] and Glengarry [31]. Note that these italicized numbers correspond with the maps found in the Ontario Butterfly Atlas. 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 T.E.A. publications and memberships are available from the address above. ******************** 2 15' 20 40 GO Wi. ... o 20 .eo 60 10 100 ta CC' LAce ONTAWfO 0..---, ..

GENERAL SUMMARY OF ONTARIO LEPIDOPTERA IN 2000 Alan Wormingon notes that the year 2000 was again exceptional for butterflies at Point Pelee National Park, with a total of60 recorded species. This is the second-highest total ever recorded at Point Pelee in a single season, second only to the incredible 65 species found in 1999 - an annual total that perhaps will never be exceeded. An annual total of 50 or more species at Point Pelee is considered significant, as it indicates that a good variety of southern immigrants have put in an appearance. Indeed southern immigrants were very conspicuous in 2000 with an early influx during the first half of May involving such species as Juvenal's Dusky Wing, Fiery Skipper, Pipevine Swallowtail, Little Sulphur, Common Gray hairstreak, American Snout Butterfly, Variegated Fritillary and Common Buckeye. The presence ofthese early immigrants, along with permanent residents, resulted in a remarkable 26 species found on May 13 alone and a cumulative total of33 species for the month. Yet another butterfly new to Point Pelee National Park was found during 2000 - the Clouded Skipper (Lerema accius) on October 30 - increasing the list ofspecies recorded here to 87. The Clouded Skipper is also a new species for Ontario and Canada. Another significant event was the major influx of Zebra Swallowtails, observed in numbers not recorded here since 1913. The 2000 season ended abruptly and unusually early on November 6 when the last species were recorded - Early Crescent, Eastern Comma, Painted Lady, Common Buckeye and Monarch.
