It measures 2 mm ({{frac|1|12}} in) long and is black in colour.[1] Christii flies live under the bark of smaller branches or twigs of dead aspen trees.[2] DiscoveryIain Christie originally discovered the Christii fly with several others in the late 1980s, but the fly was not recognised as a new species until 1997, during a survey of the flora and fauna of the Cairngorms.[3] The research was conducted for the book The Nature Of The Cairngorms, which includes 223 species mainly found there and 1,153 further species for which the Cairngorms are nationally noted.[1] Graham Rotheray of the Museum of Scotland and Dave Horsfield of Scottish Natural Heritage found the Christii fly under the bark of a decaying aspen tree near Grantown-on-Spey.[4] Since then, it has been found in Norway and two or three more times in the Cairngorms.[1] Rotheray described the Christii fly as "a superb example of a boreal species which has lain undiscovered in Scotland for thousands of years" and "a specialist species which adapted and probably came north with the retreat of the ice".[4] He also believed the fly to be a relict from the ice age.[5] References1. ^1 2 {{cite news | url=http://heritage.scotsman.com/news.cfm?id=866822006 | first=John | last=Ross |title=Welcome on the hillside for new fly | publisher=The Scotsman | date=2006-06-13}} 2. ^{{cite news | url=http://heritage.scotsman.com/news.cfm?id=865222006 | title=New species discovered in the Cairngorms | publisher=The Scotsman | date=2006-06-12}} 3. ^{{cite news | url=http://icdunbartonshire.icnetwork.co.uk/thelennox/news/tm_objectid=17280272&method=full&siteid=78846&headline=family--x2019-s-pride-as-new-fly-is-named-after-iain-name_page.html | first = Tina | last = Kemp | title=Family's pride as new fly is named after Iain | publisher=The Lennox | date=2006-06-23}} 4. ^1 {{cite news | url=http://news.bbc.co.uk/2/hi/uk_news/scotland/north_east/5069508.stm | title=New mountain species discovered | publisher=BBC News | date=2006-06-12}} 5. ^{{cite news | url=http://www.timesonline.co.uk/article/0,,2-2222410,00.html | title=Ice Age fly discovered alive and well in Scotland | first=Lewis | last=Smith | publisher=The Times | date=2006-06-13 | location=London}} External links
