About the Ontario Moth Atlas

The Ontario Moth Atlas is a project of the Toronto Entomologists' Association. The atlas currently covers about 250 species from 7 of the best-known families: Saturniidae, Sphingidae, most Erebidae (genus Catocala, Notodontidae and Arctiinae), Lasiocampidae, Hepialidae and Apatelodidae. As data accumulates, the list of species will exapnd until all of the approximately 3,300 moth species found in Ontario are included.

 

The atlas presently includes 62,000 records. The last update of the atlas was in April 2020. The atlas is updated at least every 3 months.

 

We are always looking for more records. Post records for inclusion on iNaturalist.ca or, for large batches, email the TEA.

 

Most atlas data comes from iNaturalist records. However, there is some data from Chris Schmidt of Agriculture Canada, the BOLD (Barcode of Life Datasystems) project of the University of Guelph, and from other records submitted directly to the TEA. Data from all TEA seasonal summaries since 1969 is also included.

 

We thank Bird Studies Canada for providing the shape files defining the 10,747 10 km squares shown on these maps. The shape files for counties and parks are from Ontario's Land Information Office and contain information licenced under the Open Government Licence - Ontario.

 

The other TEA insect atlases are the Ontario Butterfly Atlas, Maritimes Butterfly Atlas, and the Prairie Provinces Butterfly Atlas.

 

There will be inevitably be some errors or questionable observations, and we would like to know about this. We also welcome any questions about the atlas or suggestions for improving it. Contact the TEA (Alan Macnaughton, info@ontarioinsects.org).
