Canada is home to over 1000 species of leafhoppers. They are one of the most abundant groups of insects in many habitats, where they feed on a wide range of host plants. However, only a handful of economically important species are well-known. I will discuss some of what we know about the distribution and natural history of Canadian leafhoppers, and discuss how ongoing research, including citizen science, can lead us to a better understanding of this important and fascinating group.

Understanding the factors that determine species’ range limits is key for accurately predicting how species will shift their ranges in response to changing climates. Despite this, we still do not understand how climate constrains species’ range limits. Through a combination of lab and field experiments, and ecological modeling on different Lepidoptera species, my lab is testing hypotheses to better understand the relative importance of various climatic constraints on species geographic limits.

Deadlines for submission to our newsletter: Fall 2022 issue - Septmember 30; January 2022 issue - December 15; and April spring issue - March 15
"Controlling the DD Moth [Lymantria dispar dispar]" by Clement Kent. A 5-page article from the December 2021 issue of the TEA's newsletter, Ontario Insects.
The latest newsletter of the Alberta Lepidopterists' Guide was published in Spring 2022.
At the September 25, 2021 meeting, the new executive was elected: Bipin Dhinsa, President; Alan Macnaughton, Vice-President; and Albert Tomchyshyn, Secretary. Chris Rickard did not stand for re-election as Treasurer but will act in that position for the time being.
Latest Bulletin (September 2022) of the Entomological Society of Canada. Amateurs can join the ESC (and have access to the Society's scientific journal The Canadian Entomologist) under the"entomology enthusiast" category (as of 2022, $56.25 per year).
Rick Cavasin of Ottawa, sponsor of the Ontario Butterflies website and author of various fold-out butterfly guides, has won the Entomological Society of Canada's Norman Criddle Award. This award is to recognize the contribution of an outstanding non-professional entomologist to the furtherance of entomology in Canada. See page 132 of the latest ESC Bulletin for a full description of Rick's accomplishments.
Karen Yukich wins Ontario Nature's W. W. H. Gunn Conservation Award "for her dedication to the restoration and conservation of nature in Toronto's High Park."
A group including former TEA president Jessica Linton is working at re-introducing the Mottled Duskywing butterfly to its former habitat in the Pinery Provincial Park. This is part of an $825,000, 5-year project to reintroduce this endangered species. Currently, the mottled duskywing lives in only a few pockets in the province, including populations near Peterborough and around Oakville. See the University of Guelph announcement and the June 2021 issue of the TEA's newsletter Ontario Insects for details.
See the article Tiger Swallowtails: Making Observations in 2020 for tips on recording tiger swallowtail observations this spring and summer. In short, anyone making observations south of the Sudbury area should take pictures -- especially of the underside -- and not rely on sight observation.
The TEA seasonal summaries for 2020 and 2021 are in preparation and are expected to be released in 2022.
Monarch rearing/rescue article. This is from the January 2020 OI.
Spiders of Toronto. This is a revised version (2018) and is part of the City of Toronto's Biodiversity Series.
When Alan Wormington passed away, he left behind a mostly-completed 130-page manuscript on the butterflies of Point Pelee National Park. Ross Layberry has filled in many of the gaps, and here is the modified manuscript. We hope that in the future, it will be possible to fully complete the manuscript and publish it under TEA auspices. Contact Alan Macnaughton or Bill Lamond for more details.
An article on the Azure blues of Ontario has been published by Chris Schmidt and Ross Layberry. This article proposes big changes for the classifications of this genus. See this page for a summary of the article.
The publications "Butterflies of Toronto" and "Spiders of Toronto" have been posted online. Copies are also available in Toronto public libraries.
For inquiries about insects or our organization, please contact our general mailbox email@example.com and we will find the right person to answer your question.
The TEA is an affiliated group of ProtectNatureTO, a new group which is working towards preserving Toronto's natural heritage. Karen Yukich of the TEA is an active member of this group.
Keep in mind that all records submitted to eButterfly are plotted as exact points on the publicly-accessible eButterfly maps, unless you specifically ask for the data to be recorded as “sensitive” or “confidential.” This may be important if you are submitting records of endangered species or you are reporting data from areas for which there is no public access.
Do you have Ontario butterfly records that you could make available to the TEA? Over 400 people now contribute records to us annually, which we use to produce the Ontario Butterfly Atlas and an annual seasonal summary (Ontario Lepidoptera ) of records for each species for the just-completed year. The seasonal summary also serves as a forum for notes and articles on aspects of biology, distribution, behaviour, survey work, etc. Photographs are also welcome, especially of significant records. Submit your records, notes, articles and photographs to Ross Layberry(firstname.lastname@example.org) or Colin Jones (email@example.com). We encourage people to submit records by December 31, but records for inclusion in the atlas database are welcome at any time -- data from years ago is valuable as well.
More information on the summary, how to submit records, and a downloadable records template can be found at this link or by contacting any of the people above.
Ontario records of odonata are also welcomed. We do not have an odonata atlas or a seasonal summary at the moment, but we like to get there. More information on how to submit records, and a downloadable records template, can be obtained from Colin Jones (firstname.lastname@example.org).
Raise or collect monarch butterflies or swallowtails? Anyone who is involved in these activities needs a permit. Contact us if you are a TEA member and want to be covered by the club's permit.
Many older TEA publications are now available for free download on our publications page. This includes all back issues of our annual seasonal summary (Ontario Lepidoptera), other than the two most recent issues -- over 2,000 pages of observations spanning more than 35 years. Copies of our newsletter (Ontario Insects) from 1994 to 2015 are also available.
The Toronto Entomologists' Association (TEA) welcomes everyone who is interested in the insects of Ontario. We are an association of mostly amateur entomologists. Although our meetings are held in Toronto, we extend far beyond that in our field trips, our membership, and our seasonal summaries. Come to our meetings, join us on our field trips, purchase our publications, apply for the research grant, join us! The TEA is a registered charity and a non-profit educational and scientific organization formed to promote interest in insects, to encourage co-operation among amateur and professional entomologists, to educate and inform non-entomologists about insects, entomology and related fields, to aid in the preservation of insects and their habitats and to issue publications in support of these objectives.
Membership in the TEA
Anyone with an interest in insects is encouraged to join the Toronto Entomologists' Association. Please see our Membership Page for more details.
Did You Know?
TEA member Don Davis holds the Guiness Record for documenting the "longest migration of a butterfly." A monarch he tagged and released at Presqu'ile Provincial Park near Brighton, Ontario in September 1986 was recovered alive the following April at Austin, Texas, having spent the winter in Mexico at the overwintering sites.
