Unfortunately, I couldn't produce a custom guide for every sub-region in the province. For those who don't stray far from their home turf and want a guide that focuses on their local species, there's a simple solution. Your local Field Naturalist Club probably maintains a checklist of the butterfly species that are found in your area. Alternatively, you can consult some of the resources I've listed on my reference page and work out your own list of species for your area ( this would be a great exercise! ). Once you have a list of the species for your area, you can pick up some inexpensive stickers and use them to customize your guide with your own notes.
When you're trying to identify a butterfly you've seen, it can be tempting to just look at the photos and pick something that looks similar. Unfortunately, there are a number of lookalikes that can be difficult to tell apart, especially for the untrained eye. Even experts have trouble distinguishing some species visually. Other clues can help you zero in on the correct ID:
- compare the size of the butterfly in question to the size code in the guide
- check the flight season chart to see if the species you're considering is normally flying at the time you made your observation
- consider the status codes - is the species you're considering rare or common?
- Consult a field guide to get more precise ID criteria, and more detailed information about the habits and habitats of the species in question. This information may also be available on the Butterflies of Canada website ( see links page ). Some butterflies are localized to very specific types of habitats, and where you saw the butterfly in question can factor into the identification.
- Your local Field Naturalist Club probably maintains a checklist of the butterfly species normally found in your area which can help you narrow things down.
- Use eButterfly to get an idea of the normal range for a species you think you may have seen, but note that the eButterfly database has limited data for some areas of the province. You can help fix this by contributing your own observations ( click here to find out more ).
- If you have a photo, you can post it to one of the butterfly observation listserv groups to see if someone can help you with the ID. Alternatively, you can report your observation via eButterfly as an "unknown species" and include the photo. An expert will review your record and may be able to provide an ID. Include information about where and when you saw the butterfly in question, and any behavioral observations that may provide additional clues to its identity.
