Pacific Maritime Big Book of Bees
Created and designed by Cait Harrigan & Kath Quayle
Big Book of Bees!
This book features a gallery of native bee species that have been documented in BC’s Pacific Maritime ecozone at one time or another. The gallery is based on the comprehensive list of species published by Sheffield and Heron in 2018 together with more recent research grade sightings in iNaturalist, GBIF and the Galiano Biodiversity Life List.
Images have been collected from iNaturalist as well as from the Spencer Entomological Collection (SEC) Collection, to whom we give special thanks for allowing us to reproduce their specimen images for this book.
We indicate some attributes with the following badges:
Badge | Meaning |
---|---|
SH list | Species present on Sheffield and Heron 2018 list |
PM Evidence | Physical evidence exists for this species’ presence in the Pacific Maritime (research-grade image, or preserved specimen) |
Galiano | Evidence for this species’ presence on Galiano Island, BC |
Why we made this book
We made this book to provide easy access to information that can help you identify native bees that have been found in BC’s Pacific Maritime region. The photo gallery lets you compare your bee picture or specimen to species known to be in the region, and links to GBIF and iNaturalist maps show you where and when different species have been observed.
We focus on the Pacific Maritime region, and link out to records of the same species if they’ve been spotted elsewhere in the world. Our goal is not to duplicate functionality of well-established aggregators, but to provide different options for organizing and visualizing the same data.
Example usage:
- Select a species in the gallery
- Check out the GBIF (Global Biodiversity Information Facility) map where available
- Compare with your own observations to help identify bees
The species pages are set up to help answer “When was this species last seen in the Pacific Maritime?”

Data Completeness
Bee book gallery shows two pieces of information per species page:
- Bee image (curated by KQ)
