T.E.A. Seasonal Summaries: Ontario Lepidoptera
TEA annual summaries of Lepidoptera encountered in Ontario began in 1969, more than 40 years ago.
Please contribute your data (old or new) to these summaries and to the atlas -- see this page for instructions. Both members and non-members are welcome to contribute.
The most recent issue, for the 2011 season, includes 76 pages of records from more than 145 individuals throughout Ontario. Each butterfly species is given an individual narrative account of its prevalence, distribution, flight periods, and any change from previous years. Full colour is used for the front and back cover and 9 inside pages. Coverage of moths varies from year to year depending on the availability of volunteers.
Records from 1969 to the present are used in constructing the TEA's Ontario Online Butterfly Atlas.
Older summaries are free for download in three full-text-searchable pdf files which contain multiple summaries: 1969-1989, 1990-1999 and 2000-2007. Save the files to disk and use Adobe Reader to view the bookmarks to navigate easily to individual summaries and the components of those summaries. If these files are too big for convenient dowload, then download one summary at a time by clicking on the year desired in the list below.
Mourning Cloak Article from the 2009 Summary
Due to a printing error, the colour difference between the various forms of Mourning Cloak was not clear in the 2009 issue of Ontario Lepidoptera. An online colour-correct version of the article can be viewed here.
