More leaves....and hopefully leaf-mines, from Burry Port.

I popped out yesterday afternoon to try to obtain a difficult-to-collect naturalised Helianthus for Richard Pryce, that was growing beyond a (high) fenced-off section of the main railway line, and which I managed to do with the aid of a stick! As I was `out and about`, I had a quick walk around some nearby streets and also on a dry brownfield site (at SN451004).

1. Above: a Populus near the school at Heol Elfed, Burry Port...perhaps Stigmella sp?

2. Above: same poplar as above.

3. Above: Plantago lanceolata (ribwort plantain) - is one mine that of Asilapteryx tringipenella - with the folded-over section? Brownfield site.

4. Above: birches from the brownfield site, Burry Port.

 5. Above: two different Trifolium leaves (clovers), note folded-over section on left-hand leaf. There`s a micromoth Parectopa ononides that mines clover, but also various diptera - I`m not sure!

Finally, a change from leaves! A clouded yellow, restless as ever, was seen periodically at the brownfield site, where I also spotted this little bug. It`s the ant damsel bug Himacerus mirmicoides (photo below - click on it to enlarge).

Not appropriate light trapping weather - unfortunately - this week. If the forecast is favourable, please do trap (it`s not light until quite late now and moth numbers are diminished - but may include some seasonal `goodies`).


  1. Poplar - might be Stigmella trimaculella but I'm not certain.

    Plantain - agree with Aspilapteryx.

    Birch - the blotch is a Phyllonorycter, not sure which one. The gallery mines are probably Lyonetia clerkella.

    Clover - the right hand ones look Dipterous but the left hand one does look good for Parectopa. Are there any Carms records of it? One of the flies makes a similar mine, but less brown.

  2. Thanks George. Parectopa is not listed for Carms on Sam`s 2013 list.

  3. It's supposed to be easier to find as a mine rather than an adult (though I've had it in my Cardiff trap) - but as a potential new VC record I guess it would need rearing through, due to the similarity of some of the fly mines. Or you could try sweeping for adults next year.

  4. Thanks again George. I`ve chucked the leaf (it`ll be somewhere on my compost heap). I`d be lousy rearing it anyway! We`ll await Sam`s comments on this particular blog, but I suspect that the putative record will have to be square-bracketed or pended at best.
    No leaf-mining today - or trapping tonight....rain, rain and more rain!

  5. The Poplar ones look rather non-Lep to me, but maybe that's because they are old. You really need to look at them carefully with the website so as to compare various Diptera and Hymenoptera. If it's a sawfly you'll need to check the larva for the degree of "sclerotization of the anal ring" :-)

    I agree with George about the Clovers. The right one is definitely an Agromyza; the left does look a lot like Parectopa but the photo doesn't quite show enough detail for confident ID and you really need to note details of the frass. Please put it in as a record, but I'll have to pend it until we get confirmation: it's a cracking-looking moth so well worth checking for at another time. Sorry!

  6. No probs Sam and thanks for trying.
