Butterfly and Moth Atlases - A Partial List

Note that the links below are to the specific web pages where the maps are the found, and not the home pages of the projects or organizations.

Note also that sites differ as to how much information they have available to be mapped. Some sites are new and have few observations to map.

Thanks are due to Kendra Serbinski, a student at Wilfrid Laurier University, for gathering the information on this page.


Alberta The E.H. Strickland Entomological Museum at the University of Alberta has data on 225,000 specimens of all types of insects. The individual observations can be displayed as a list, including latitude and longitude for each. The observations can also be displayed as a 2-inch by 2-inch map, with the ability to zoom in.

BC Butterfly Atlas

Maritimes Butterfly Atlas (provinces of NB, NS, PEI)

Ontario Butterfly Atlas (TEA)

Canadian Biodiversity Information Facility (Government of Canada)

e-Butterfly (University of Ottawa): Enter a species and click on "Find Your Records on Map." This will display a map of point observations for that species from across Canada.

United States

Butterflies and Moths of North America (BAMONA): Pick a species, choose "United States" (and, optionally, a state and a county), click "Apply", and a species page will appear with a sightings map at the bottom. Regardless of the state or county chosen, the map is of point observations of that species for the entire US. Species lists are provided for each state/province and, in the US, for counties as well.

Butterflies of North America (sponsored by the Prairier Wildlife Research Centre): Pick a state, then pick a species, and a species page with appear with a county map at the bottom. The map will show counties in that state where the species has been observed. However, the links work only for 5 states: Alabama, Alaska, Arkansas, Arizona and Calfornia.

Vermont Butterfly Atlas
We Butterfly. This is a project of the North American Butterfly Association (NABA). It shows maps and charts of data on butterfly species seen over the long history of NABA butterfly counts in the US and Canada. The data is from 1980 to 2014.
Maine Butterfly Survey. Shows maps of each species by township, of which there are about 400 in the state. Thus each township is about 12 km by 12 km. Shows data on flight periods (number of records for each species for each one-fifth of a month). Displays the individual records for each species.
Connecticut Butterfly Atlas. Maps are shown for each species by blocks (one-sixth of a USGS quadrangle). A block is about 5 km by 5 km.
Massachusetts Butterfly Atlas. Shows maps of each species by block (of which there are about 1,100 in the state).
The Butterflies of Massachusetts. Provides information on newer sightings, i.e., beyond the atlas period. Map is by species by town. There are 301 towns in Massachusetts, so each town appears to be for an area of about 7 km by 7 km.
Kentucky Butterfly Net. The link "data queries by species" shows maps of each species by county (120 in the state), along with flight period charts, earliest and latest dates in the year, and the raw data underlying the maps (sometimes including GPS coordinates). The link "data queries by location" provides the user with a map of the state showing its counties. By clicking on a particular county, the user can access the species list for that county.
Butterflies of North Carolina. The maps are of each species by county. In addition, flight period graphs, flight period charts, and earliest and latest dates are provided for each species for 3 regions of North Carolina (Mountains, Piedmont and Coastal Plain). This information is available separately and in the form of a pdf of about 190 pages which is updated annually. The pdf also includes detailed remarks on each species. The raw data is also available. An accompanying photo site points out identifying marks for the more troublesome species.
Moths of North Carolina. Announced in Lep Soc News 2017#4. Similar in content to Butterflies of North Carolina website.

United Kingdom and Elsewhere

Big Butterfly Count (sponsored by Butterfly Conservation): Pick a species, a habitat (7 choices and "All"), and (optionally) type in a location, and a map of where that species occurs in the United Kingdom will appear. On the map, click on the butterfly symbol for any area and an info window will display the species list and numbers of records. These maps seem to be very detailed as "location" apparently can be as detailed as a part of a city (check this).
