On E-Flora BC, we map the data provided to us from several institutions and other sources, including specimen records, observation data, and photo records--provided that these sources include coordinates (georeferencing) with their data. This information in provided in database format, from which we extract the species name and location information, as well as other associated information.
Until recently, ten data sources (databases) were used to map vascular plant species distributions. These are
The Illustrated Flora of British Columbia (IFBC)
The BC Conservation Data Centre records (CDC)
Consortium of Pacific Northwester Herbaria (CPNW)
Royal BC Museum (V)
University of British Columbia Herbarium (UBC)
University of Alaska (ALA)
E-Flora Photo Records
Biogeographic Ecosystem Classification (90% observation data)
Invasive Alien Plant Program (observation data)
We have now added two new data sources: the specimen data from Marie-Victorin Herbarium (MT) and the Green Plant Herbarium (TRT), each of which have many BC records.
You can view a list of all data providers for any E-Flora maps by opening the legend associated with the full-sized interactive maps.

According to Schmidt, the Elephant Hawk Moth "has become quite widespread in the lower mainland since its introduction in the mid 1990's. They are well-established and numerous in some areas."
Both the moth species and the host plant are introduced species in BC and Canada.
Identification of the moth larvae was made by Chris Schmidt.
Identification of the plant in the photo was made by Andrée Bernard and Jamie Fenneman.
