In addition to the Scottish wood ant, several Scottish species of invertebrate exist that are otherwise rare in the UK and important enough to have a specific "Action Plan" to provide protection. These are five species of ant and bee, six moths and butterfly, five flies and a single beetle (the reed beetle) and snail (the round-mouthed whorl snail, "Vertigo genesii"). Northern colletes is a rare species of bee, the most significant British habitat for which is in the Outer Hebrides, where there are more than ten colonies. Scotland is also the UK stronghold of the Blaeberry bumblebee, and the Bumblebee Conservation Trust recently created the world's first sanctuary for this genus of insects at RSPB Vane Farm Nature Reserve near Loch Leven. The bumblebee "Bombus jonellus" var. "hebridensis" is endemic to the Hebrides. In 2010, a colony of the beetle "Meloe brevicollis" was found on the island of Coll. The species is otherwise extinct in Scotland and is also flightless, raising the question of how the colony arrived on the island. The northern February red stonefly ("Brachyptera putata") has recently lost its range elsewhere in Britain and is now it considered to be a Scottish endemic.
