Hmm, it Suillia parva/flavifrons species-group ! If scutellum is bare ventrally should be S. flavivrons, if hairy so S. parva

Hooray ! Thank You Andrzej, we have a name  The scutellum is ventrally hairy, so it's parva. Thank You once more.Jari |

Not necessarily: it could be dawnae, which is not easy to separate in females. |

Hmmm, that would be interesting. As far as I know Suillia dawnae is found only from British Islands  Everything is possible nowdays but I would be a bit sceptic with that. The second thing is, that this information is based only what I can find from Fauna Europaea database.Jari |

I find dawnae much more frequently here in France than parva; just because I first found it in Britain does not mean it cannot occur elsewhere. The character to separate the two (which may not always work - limited material to try it on !) is whether the pruinosity on the frons reaches past the orbital bristles (parva) or not. The position of the orbitals may also work: in dawnae these are well forward of the anterior ocellus. Good luck ! |

Thanks Phil for your comments ! Right, S. dumicola described from UK was found in Poland some years ago ! What about the distribution of S. dawnae in France. Is S. dawnae more limited to highlands or lowlands areas ?. dr. A. J. Woznica, Institute of Environmental Biology, Wroclaw University of Environmental & Life Sciences |

I'd say parva on the strength of this pic. I have a feeling (nothing more than that yet without checking my collection) that dawnae is more lowland and parva more "alpine"...but don't quote me ! Incidentally, since I named it after my ex-wife, I'd be happy to sink it as a synonym one day ! |

I agree fully with your opinion that S. parva is more " an alpine" species There is a small pseudovibrissa seen at the last picture !. I've noted it in more specimens !
