Night & day

Evening walks in the Penyclawdd/Cwmcarvan area (under-recorded for Micros) on 29th & 30th May were followed by MV trapping at Dingestow Court.  Both days/nights were pretty good.

Penyclawdd Wood 29/5 held clouds of Glyphipterix simpliciella and Coleophora caespititiella, but also some more notable species such as Cochylis nana (poor photo, 3rd VC35 record), Ancylis diminutana (photo) and Ectoedemia sphendamni.  Tiny round mines of Incurvaria pectinea (mostly excised but three with dead larvae) were new for the Dingestow area (Micro #509 here).

The MV in Dingestow Court garden produced 70 species on 29/5, with Lime Hawkmoth (photo), Orange Footman, 4 Plutella xylostella, 1 Nomophila noctuella, 1 Deltaornix torquilella and 1 Pseudoswamerdamia combinella among the highlights.  Star species was Anania (Opsibotys) fuscalis (photo) new for Dingestow (Micro #510) - a wanderer because Yellow Rattle doesn't grow here.  The origin of this moth is a bit of a mystery, as there are only 10 previous Gwent records and several of them are from good migrant/wanderer years.

An evening walk at GWT's Croes Robert Wood on 30/5 was a bit slow from a micro standpoint because there is little low foliage for tapping.  A couple of Eulia ministrana and the county's third record of Grapholita tenebrosana (photo) were the highlights, but all 13 species I found were new for this nearly blank tetrad.  I then headed to the relatively well-recorded Trellech Hill Quarry, where 8 Micros were new for the site, with Ancylis uncella (photo) the most noteworthy (4th county record).

The Dingestow Court MV was quieter on 30/5, with 50 species.  A May Highflyer (photo) was the star Macro, with 3 Nematopogon metaxella (photo) and a Coleophora mayrella being the best Micros.
