I'm sure I'll get the hang of these next week, but this week I need help ... T. rufescences maybe ?

I don't think it's rufescens; the curve should be notably more hooked for that one. Is the body when dry blackish or brownish? I suppose I should ask how it compares in size to major/rufulenta too. London's Insects http://londoninve...hostia.com |

It's quite a big one, but not major size. I actually had it first down as major. Haven't looked at it dry yet, but it immediately seemed fairly brownish (but this is a 2 year old malaise trap ex) - the hiemalis in the same tube was however definitely much darker (and smaller). |

Hmm... this one is trickier. Form of the ovipositor suggests T.pappi, but this species is known from Poland, Sweden and Hungary, so doubtful. It could also be not very typical saltator, or something else at all - inner genital structures could help to say more. Could you also make a close up of antena? |

Here are the antenae, no setae on the pleuron, about 7mm long. |

I settled for saltator for most of my specimens now. It appears the most common species around here at this time of the year. Thanks, Joris |
