2023 Butterfly counts / Odonate counts

Butterfly and odonate counts -- whose aim is to produce a list of species observed and the number observed for each -- are a great opportunity to improve your identification skills. If you don't feel your level of expertise is high enough, you can always check with the count organizer. Often you can go along with a more experienced person. I hope you'll join at least one in your neighbourhood.

The Toronto East butterfly count (usually held on July 1) is a TEA activity. All other counts are by other people or organizations, and we publicize them as a service to our members.

On some of the counts refreshments or camping facilities may be provided. Don't hesitate to contact the organizers if you have any questions. They would appreciate you letting them know as soon as possible if you will be participating, so they can plan more efficiently.

Dates are subject to change! Please check with the count organizer in advance. Also, at some counts people meet first thing in the morning, and then disperse; at others, people meet at noon; at still others, people meet at dinner. And there are counts for which the count area is divided up ahead of time among different individuals, and they may not meet at all on that day.

Everyone is welcome, whatever your skill level. Note that many of the butterflycounts are done for the North American Butterfly Association (NABA) and that there may be a nominal charge for participating.

Please be prepared for the count activity with sunscreen, water, hat, food, and other items suggested by the count organizer. A butterfly net is also helpful, if you have. And if you have any small clear plastic containers to butterflies in to show other people what you have caught, they would be helpful too.

2023 "Caterpillars count!" activities

Caterpillars Count! is a citizen science project for measuring the seasonal variation and abundance of foliage arthropods like caterpillars, beetles, and spiders. Participants collect data by conducting surveys on trees and shrubs and recording all of the arthropods observed. Here is a map of sites in Ontario, most of which are in the GTA. Ecospark is the organizer of the GTA sites -- see the project's iNaturalist page. Here is one of these events:

- Middle Mill (nearest address 44 Beechwood Drive, East York, Toronto: a project of Toronto Nature Stewards), Wednesday mornings - 9:00 - 11:00 or Thursday evenings - 5:30 - 7:30 until end of September. Donna Rice, donnarice456@gmail.com.
