Distribution Map for: Swallowtail
The map below shows the distribution of the Swallowtail. If the species distribution is shown, the National Grid and the Irish National Grid each consist of a number of 100 x 100 kilometre grid squares and the distribution is shown at a resolution of 10km. In a grid reference such as SU317201 (used in the site listing below the map), SU is the grid square, 317 is the easting and 201 the northing. Click on the site name for more detail about the site.
The distribution data (1995-2004) has been made available through the generosity of Butterfly Conservation. Any subspecies distribution is taken from the book British and Irish Butterflies, by Adrian Riley.
