Another week, another leaf mine – in fact, lots of mines in the glossy, lush leaves of Hart’s-tongue ferns (Asplenium scolopendrium).
I have actually blogged about these before (Leaf mine in Hart’s-tongue, January 2018) but those finds were made in Somerset and I’m now finding lots of these mines in my local area in south Wales. The mines are made by the larvae of the fly Chromatomyia scolopendri, one of the Agromyzidae family of flies, and their long, winding gallery mines are unmistakeable.
You can read more about these flies on the newly launched Agromyzidae Recording Scheme website, and, if you’re interested in finding out which leaf mines to look out for and when, the scheme has a page that lists which species are most commonly recorded each month. Can you find Chromatomyia scolopendri mines in your area?
