Jones ................................................ 82 Ontario Lepidoptera 2003-2004______________________________________________________________________________ GENERAL INTRODUCTION I would like to begin this year’s annual Lepidoptera summary with an apology for the delay in its production. For a variety of reasons, the compilation and production of data from 2003 and 2004 was met with various challenges. Personally, I had a variety of set-backs with the butterfly and skipper section and the original delay in the production of the 2003 summary led to a decision to combine the 2003 and 2004 seasons in one issue. Also among the challenges was the unfortunate inability to obtain a new compiler and editor for moths resulting in the lack of a moth section in this particular issue. I would like to thank both Jason Dombroskie and David Bree for the considerable amount of work they have already done at compiling and editing the data submitted and would invite anyone interested in fulfilling this role to step forward so that we can hopefully get back on track for the moths beginning with Ontario Lepidoptera 2005. Compiling, editing and producing these summaries is a lot of work, but it is also interesting and rewarding work and it would be a real shame not to continue the work of past compilers at summarizing the valuable contributions of so many TEA members who are studying and recording their observations of moths in the province of Ontario. This year’s issue of Ontario Lepidoptera includes a number of valuable and interesting notes and articles on butterflies and skippers in the province as well as the printed summary which focuses on noteworthy records for the season. Data for all records of all species received for the year (much more data than can be included in the printed summary!) will be included in two tables available as downloadable PDF files from the TEA website (www.ontarioinsects.org). Members will recall that in Ontario Lepidoptera 2002, these files were located on a CD inserted at the back of the issue. As most members have access to the internet, however, and as these files are relatively small in file size (i.e. are easily downloadable even with a dial-up connection) it was decided that it made more sense to save the added expense of the CD production and simply make the files available via the internet. For any members without access to the internet, simply contact me (contact information below) and I will be more than happy to send you a printed copy of the tables. The contents of this publication have been checked for errors and accuracy as much as possible. Please notify me of any corrections of errors or omissions, and these will be included in future issues of Ontario Lepidoptera and incorporated into the database. Work on the compilation and production of Ontario Lepidoptera 2005 has already begun but we will be accepting additional records, notes and photographs from the 2005 season until September 30, 2006. Records and notes or articles for the 2006 season should be submitted by February 28, 2007 to: Colin Jones Box 182, Lakefield, ON K0L 2H0 Tel: 705-652-5004 email: [email protected] or [email protected] Information on how to submit records can be obtained from the compiler – the format is basically the same for butterflies and moths with minor differences. 1 Ontario Lepidoptera 2003-2004______________________________________________________________________________ THE POWER OF DATABASING OUR RECORDS AND HOW YOU CAN HELP Most people these days have a personal computer at home and use it for record keeping. In order to greatly speed up the process of databasing records submitted for Ontario Lepidoptera we are asking that contributors submit records in electronic form, preferably in a spreadsheet (e.g. Microsoft Excel, Corel Quattro Pro) or database (e.g. Microsoft Access, Corel Paradox) format. There is also a technological advance that has become much more accessible in recent
