Next Meeting

Sunday, April 23, 2017. TEA meeting from noon to 2 p.m., with a public lecture at 2:30 and a display from 11 a.m. to 4 p.m.

Plan for a full day at the ROM, but note that this is a Sunday -- not our usual meeting day! There is a bug rearing meeting, a display of live bugs in the ROM galleries by a Sault Ste. Marie insectarium, and a public talk by the U of T author of a new book on Monarchs. Come early, perhaps at 11, if you want to attend all 3 events.

You must pay for ROM admission, unless you are a presenter. Admission prices are here. Purchase tickets here or at the door. Advance purchases of tickets by TEA members will receive a 20% discount, but you must enter the promo code (from the TEA email, or contact info@ontarioinsects.org). If you want to attend the Monarchs lecture, please also register for that, although there is no additional fee. Seeing the ROM's special Blue Whale exhibit requires a higher ticket price, but the TEA discount on tickets purchased in advance applies to the full price.

The TEA's fifth annual meeting on rearing insects and spiders (or other arachnids) is from noon to 2 p.m. We invite anyone who has reared these creatures for display, for conservation or just out of interest, to share their experience. Live specimens, PowerPoint programs, displays of rearing equipment, mounted specimens or prints are welcome. Please contact Antonia at antoniag@rom.on.ca if you are interested in presenting. One of the presenters is John Dedes, who works at the Great Lake Forestry Centre and supervises the Insect Production facility. He will speak about the quarantine facility and how they rear invasive species, and test and rear proposed biological controls. John is the CEO of Entomica, an insectarium which is having a display at the ROM which is open to the general public (see below).

At 2:30, there will also be a ROM Connects lecture by Dr. Anurag Agrawal, speaking about his new book Monarchs and Milkweed. This lecture will be in the ROM theatre. Pre-registration will be required but there is no cost for this lecture. Copies of the book will be available for sale at the lecture.

Entomica, an Insectarium in Sault Ste. Marie, will be at the ROM's Currelly Gallery from 11 to 4. Entomica will also be there Friday starting at 5:30 and all day Saturday. Entomica is looking for a few volunteers to help them on the floor for all days. If interested, please contact Antonia or info@ontarioinsects.org. Comfort handling live insects is preferred but not essential.



Other Insect Activities and News

December 2016 bulletin of the Entomological Society of Canada.

A new 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.

Deadlines for submission to our newsletter: April 2017 issue - March 15; September 2017 issue - August 15; and January 2018 issue - December 15.

The publications "Butterflies of Toronto" and "Spiders of Toronto" have been posted online. Copies are also available in Toronto public libraries.

Read more Ontario insect news: see the Fall 2016 newsletter of the Entomological Society of Ontario.

Our seasonal summary for the year 2015, Ontario Lepidoptera, was published in April 2016. The 2016 summary is expected to be published in March 2017.


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 55,00 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 Online 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(rosslayberry@yahoo.ca), Jessica Linton (JessicaLinton86@gmail.com) or Colin Jones (colin.jones@ontario.ca). 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 (colin.jones@ontario.ca), 705-755-2166.


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

Ontario Lepidoptera 2015 appeared in print in April 2016: the latest of our butterfly summaries; moths are also included in this latest version in the form of a short report by Chris Schmitt of Agriculture Canada on notable observations.

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 2014 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.
