Diasemia reticularis (not in Carms!)

Chris - what an excellent record! For interest, below is a pic of an individual I trapped in North Cornwall on 27th July 2010, which was new for VC2. Like yours, this was away from the coast and none of the trappers on the south coast caught this species that year, so maybe it's a species which tends not to hug the coast?




Best wishes

  1. George, many thanks for your post. I'm still trying to get my head around the idea of such a seemingly fragile creature travelling (presumably) such a great distance. Also surprising that it was new to VC2 when you trapped yours in 2020. Apparently mine isn't the first record for Carms. I would be interested to know if it's been recorded in VC41.
    Best wishes Chris

  2. I believe, albeit without Jon's Pyralids of Carms write-ups to hand, that D reticularis was briefly resident in coastal Carms some time in the late 19th or early 20th century. I may be misremembering!

  3. We have one Glamorgan record, from Margam on 10th August 1956 (specimen in NMW collection).

    I think the one I caught in Cornwall was the only specimen recorded in the UK in 2010, so it's certainly a rare beast.

  4. E Kaye had it at Laugharne in 1870 (article in The Entomologist) - I provided Jon with that record (and many others of migrants in that good migratory year) some 10+ years ago. Kaye also had Diasemiopsis ramburialis at Laugharne, which was resident in SW coastal England at the time, and Donovan certainly thought the same for Pembs...so it could have been a Carms resident too.
    There are actually three Glamorgan records of D. reticularis - Leech in 1880, and two specs at NMW from Porthcawl (10/8/1950) and Margam (Aug 1956) - latter info provided by Barry Stewart to me when I was updating the Carms Pyralids series (to appear in the Carms Moth Gp Newsletter very shortly). The Glamorgan info will appear in the new Glam moth book in due course.

  5. Thanks Ian - I'd forgotten that my copy of the GMRG database in MapMate is missing some of the historical records.
