Cardiff City mining

The easternmost part of the Cardiff Unitary Authority is in VC35 (Monmouthshire), although not the old Gwent.  I treat it as part of my VC35 patch!  A lunchbreak wander around St Mellons from the NRW office produced a good range of miners, including several of interest.  Highlights among >20 species were Phyllocnistis unipunctella and Stigmella trimaculella on Poplar, Phyllonorycter esperella on Hornbeam, and Stigmella glutinosae on Italian Alder.  The Phyllocnistis and Phyllonorycter only had Dingestow/Monmouth records, S. trimaculella was found new for the county this year, and S. glutinosae has only one previous county record.  That sole record of S. glutinosae came from Allt-yr-yn (ST28Z) in Newport, which is the only site in south-westernmost VC35 with a decent leafminers list, thanks to a visit by Dave Slade in 2003.  Welfare Park in Rogerstone also has a few Stig/Phyllo records, but there is huge scope for finding notable Micros in this part of the county.

    Well done. I've never seen the Stig on alder. The Phyllocnistis seems quite frequent in the Cardiff Docks area (VC41 but not far from your site).

    Interesting, as always. I had Phyll. stettinensis on Italian alder yesterday. It seems that several spp that occur on the native common alder can use this introduced tree too.
