Notes:

Anyone in Scotland is urged to revisit the sites listed above and any other possibilities. Negative reports are welcome.

There is a long history of glow worms on the Isle of Cumbrae in the Firth of Clyde, as listed above. The Director of the Marine Biological Station at Millport told me in 1991 that there were still glow worms to be seen on the island. He speculates that they may have drifted there long ago on floating vegetation from the mainland. Further reports are regularly received. You can read a 1912 paper about the Cumbrae glow worms here.
