Abundance (Number of adults) The numbers of adults reported per species since 1990 have been sorted to show the relative reported abundances of species. |
Distribution (1km Squares) The number of 1km squares in which each species was reported since 1990 have been sorted to show relative distribution. This doesn't of course imply even distribution of any species - some, such as the chalk-loving species can only be found in the south. |

| Number of Records The number of records for each species submitted since 1990 have been sorted to show which species have been more often reported than others. |
Local Abundance (Adults per record) The numbers of adults reported per species since 1990 was divided by the number of records for that species to determine the average number of adults per record. This is a crude measure of local abundance - i.e. how many are seen together. |
