Past Meetings, 2022-23

Saturday, April 22, 2023. 1:15 pm - 3:00 pm. By Zoom.
THE ECOLOGY AND EVOLUTION OF EYESPOTS IN CATERPILLARS
Thomas Hossie, Trent University

See video of the meeting. The caterpillars of many lepidopteran groups possess distinct eye-like markings. In fact, caterpillars with eyespots can be found on every continent except Antarctica. Intuition and conventional wisdom tells us that eyespots protect caterpillars by scaring away predators. What is our evidence that this is really the case? Do eyespots really confer protection? Do insect-eating birds perceive these markings as eyes? What other traits or behaviours might be involved in the ruse? Why do eyespots evolve in some species but not in others? Using a combination of approaches we have tried to answer these questions to gain a better understanding of this captivating antipredator strategy.

"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 December 2022 (the fall issue).

At the September 25, 2021 meeting, the executive was elected for a 2-year period: 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.

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 2020-2022 are in preparation and are expected to be released in 2023.

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.

Contact us

For inquiries about insects or our organization, please contact our general mailbox info@ontarioinsects.org 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.

 
Try out www.e-butterfly.org, a website for entering and displaying butterfly records put together by Maxim Larrivée of the Montreal Insectarium. The TEA is one of the sponsoring organizations. All Ontario data is provided to the TEA seasonal summaries and butterfly atlas project, so “eButterfly” provides an alternative way to store and submit your data. The hope is that this will be easier than entering the data yourself on a spreadsheet, as his site saves each person’s own past butterfly monitoring sites and allows the species observed to be checked off from a provincial species list. eButterfly now accepts records from all across Canada and the US. The TEA has received about 123,00 records records from eButterfly, which is about 20% of all data used in the TEA's butterfly atlas.

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.

Records needed

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. 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.

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 (colin.jones@ontario.ca).

MNR Permit

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.

Our Publications

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 2020 are also available.

Our Association

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.
