Lateral view. Possibly Phasia sp. Another view on my website.

If it is a phasiine I'd guess it was closer to Ectophasia (no petiole on veing-M) but it is very hard to guess the size here. It looks small to me - have you checked if it has a subscutellum? |

The other picture shows an open topcell, so this must be, again, Opesia. Theo Zeegers |

Grrrr Opesia ... I was trying to think what else it could be because Ectophasia seemed such a silly suggestion for something that looks so small.  Does the time of year suggest O.cana? Ironically, I have an Opesia grandis in a box next to me on the desk - first record for the UK. |

Opesia grandis from UK ?? Quite a surprise. Well, then you can check the genus, at least Theo |

Yes, I was called on to confirm the identification last year. It keys to Opesia cana in Belshaw (1993) but the collector noticed that the flight period was wrong for O.cana. In Tschorsnig & Herting (1994) it keys easily to O.grandis  I emailed photos to Peter Tschorsnig and he said it was beyond doubt and a very good record indeed. The same collector (Ivan Perry) also took Bithia demotica (another new to the UK) in the same year and so we all think he has the 'magic touch'!  |

I checked the Hungarian literature on this genus, from these photos it is difficult to get beyond genus level. Interestingly O. species are supposed to be rare in Hungary, it is interesting that I got two records from two different areas in one year. Theo, Chris thx for you help with this and other recent threads posted by me. Edited by Xespok on 04-05-2007 07:15 Gabor Keresztes Japan Wildlife Gallery Carpathian Basin Wildlife Gallery |

I think Opesia spp. are rare wherever they occur. Which either means they really are very rare or very localised ... or we just don't catch enough because we're looking in the wrong places or using the wrong techniques! |
