BIMBY finds diversity and common ground in 2024!
With an estimated 300 species, butterflies in Canada are diverse and colourful. However, like many insects and wild pollinators in Canada, many are endangered or at risk of extinction. BIMBY is a community science project that invites volunteers to help document butterflies in Canada on iNaturalist, a community science platform, to help butterfly conservation and provide valuable data for the scientific community.
After a successful two years of engaging volunteers, called BIMBY Seekers, from British Columbia, BIMBY went national in 2024.
Important Information
-
Insects are by far the most abundant animals on Earth, yet more than 40 per cent of insect species worldwide are threatened with extinction. They are essential to ecosystems that humans depend upon — pollinating plants, providing food for other creatures and recycling nature’s waste.
In Canada, dozens of butterfly and moth species are at risk. They face pressure from habitat loss, widespread pesticide use and climate change. BIMBY is helping scientists better understand how we can help safeguard these essential species.
-
From June to November, BIMBY Seekers participate in the BIMBY Speaker Series. Experts in community science, butterflies, native plants and the state of biodiversity in Canada will share their knowledge and experience.
Here are the links to the Speakers Series:
Kirstyn Eckhardt — An introduction to Canada’s butterflies
Michelle Tseng — BIMBY data reveal new insights into butterfly behaviour
John Reynolds — BIMBY and scientific research on butterflies in Canada
-
Seekers from different cities meet, catch up and exchange notes with each other and BIMBY committee members.
-
At the end of each year, we wrap up Seekers’ accomplishments with a final report shared in November.

Like most insects, butterflies are threatened by a lack of suitable habitat, pesticides, pollution, and climate change. Fortunately, there is a lot we can do to reverse the decline of butterflies. One of the simplest and fastest ways to help butterflies is to take pictures of them.
Canada is home to almost 300 species of butterflies and it’s often the rare species that need our help the most. BIMBY 2024 will train and support Canadians from coast to coast to photograph and monitor butterflies.UBC Ecologist, Michelle Tseng
About the Butterflies in My Backyard (BIMBY) project
In 2022, the David Suzuki Foundation, in partnership with UBC ecologist Michelle Tseng and UBC Botanical Garden associate director Tara Moreau, invited residents of British Columbia to help find butterflies throughout the province.
According to John Reynolds, conservation ecologist at Simon Fraser University and past chair of the Committee on the Status of Endangered Wildlife in Canada, “BIMBY seekers created data that will be used by conservation biologists to create policy to protect the most vulnerable butterfly species.”
Highlights of BIMBY 2024
- National reach and participation: More than 800 Canadians from 10 provinces and two territories joined the BIMBY project. Over half of the 2024 Seekers made 35,614 butterfly observations in 2024.
- iNaturalist insights: BIMBY’s 2024 contributions made up 26 per cent of all butterfly observations in Canada on iNaturalist, helping fill a vital data gap in Canada’s biodiversity monitoring.
- Research grade: Thanks to the 1,004 identifiers on BIMBY iNaturalist, over 25,000 observations were made “research grade” in 2024.
- Species coverage: Participants documented more than 231 butterfly species, representing 75 per cent of Canada’s known species — a notable achievement for community science.
- Focus on endangered species: BIMBY Seekers observed six of Canada’s 13 endangered butterfly species, including the rare Behr’s hairstreak, monarch and Mormon metalmark. British Columbia participants were especially successful, spotting four of the six endangered species found in the province.
- Impact of introduced species: BIMBY highlighted the widespread presence of non-native butterflies, such as the cabbage white and European skipper, showing how introduced species have integrated across multiple provinces and affected local biodiversity.
- Provincial leader: Despite a cold, rainy spring, observations from Seekers in British Columbia accounted for 70 per cent of all butterfly observations within the province, showcasing the dedication of local volunteers.
- Data powerhouse: The data from BIMBY provide a robust resource for scientists, conservationists and policy-makers, enabling more accurate monitoring of butterfly populations and their plant associations throughout Canada.
- Plant-butterfly relationships: Observations documented 7,677 instances of butterflies interacting with specific plants, providing valuable insights into host and nectar plant preferences, essential for habitat-conservation planning.

Quotes from BIMBY Seekers:
Eric Habisch
“I love butterflies while observing them in their native habitat. In 2023, I saw migrating monarch at Boundary Bay June 25, Becker’s white in Hope July 25, the grey hairstreak in Pitt Meadows August 1 and closing off the 2023 season with a hike up Cypress Mountain with Steve Ansell was great.”
Courtney Ashford
“On my hunt for butterflies, I have become so much more aware of the environment and the life that surrounds me. I was taken aback by how I notice so many more insects now — bees, dragonflies, moths, flies and, of course, butterflies. I also have gotten to learn so much more about plants and trees (both native and invasive) and the importance and interplay between them and other species.”
Jim Lawrence
“A favourite photo from the BIMBY experience is not my photo of a Kootenay butterfly but one of my granddaughters. To me, this illustrates how respect and appreciation for our winged friends spreads around.”
Sue Elwell
“There are so many butterflies that are exciting to see but for me this year it was the Rocky Mountain Parnassian. Having found a breeding area so accessible meant that it was possible to get good pictures of a beautiful butterfly that is in the one per cent of butterflies. This was a highlight for me.”
Shirley Morrison
“How do I even begin to describe what this experience of seeking butterflies has been like for me this season? To be able to get out in nature and combine it with my love of photography has been priceless. It’s been a true joy learning more about how important plants are to the whole ecosystem. I have a new appreciation of how important even the common dandelion is. It’s one of the first nectar plants to bloom in my area, and I’m still finding butterflies on late-blooming ones at the end of the season as well.”
As I observe my surroundings, I am acutely aware of the impact of climate change and the deterioration of our planet. This crisis reverberates across all life forms — plants, insects and animals alike. Through our work on the BIMBY project, I aspire to make a meaningful contribution toward the protection of butterflies throughout Canada.

Kirstyn Eckhardt recently graduated with her M.Sc. in entomology, for which she studied the growth and development of an endangered grassland butterfly. She lives in Manitoba, Canada, and spends much of her free time seeking out and photographing butterflies.
Sue Elwell
Sue Elwell is a retiree who has lived with her husband in Princeton, B.C. since 1975 and has always been interested in nature. After “retiring,” she bought a camera and took up bird watching. This led to joining BIMBY in 2022 and becoming enthralled and obsessed with butterflies!
FAQ
-
It is fine to use “Obscured.” “Open” is preferred, but it is okay to flag the location as “Obscured.”
-
Plant associations should be done when the butterfly is either feeding or laying eggs.
-
They might be puddling, but no plant association required.
-
Yes, but it will be registered as a “casual” observation as it can’t be verified.
-
Feel free to upload all photos, regardless of the quality. If the photograph is not good enough, the observation may not reach research grade.
-
This should be four separate observations as they are four individual butterflies.
-
There is no need to select the BIMBY Project during an upload as your observation will automatically appear in BIMBY.
-
A single observation will add itself to all relevant projects depending on the filters that have been set up.
-
Yes.
-
Ideally yes, but cultivated plants will be registered as “Casual” and will not get research grade status.
-
You do not always have to join a project for your observations to show up in another project. Consider a “project” more a search with filters, such as “Butterflies and Ontario.”
Some projects collect any public observations that meet whatever their criteria are. BIMBY has a criterion that it only takes those from members.
-
You should upload four different observations, and add the goldenrod to each observation as a plant association.
