Curry RHC Ancaster P.P = Povincial Park; c.A. = Conservation Area 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. I Occasional Publication #'s 10 through 27 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 1994. 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). 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.

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).

A late frost on June 3rd dipped well into parts of southern Ontario. A heat wave June 16 - 18 sent temperatures soaring to 36°C at several locations including Toronto. Sault Ste.
