Seen on 20 may 2011 in agricultural grasslands area border with Poplar -Willow and reedlands. Is this possibly Hybomitra lundbecki??

How long are hairs on 1st antennal segment? As long as antennal segments 1+2 or very short? Libor |

They are about as long as antenne segments 1+2. |

So, I see only two possibilities: Upper facets strongly enlarged, clearly separated from lower smaller facets, 1st antennal segment yellowich to yellow-brownish = H. ciureai. Upper facets not sharply separated = H. muehlfeldi. (I have not male ciureai in my collection, so I cannot compare...). Libor |

I donot see a sharp division between larger and smaller facets only gradual differences after checking all pictures in the series I made. But my pictures are not showing sufficiently the frontside. Hybomitra muehlfeldi is called here the "peat" hybomitra. The area I located it is a rather moist heavyclay area. Does this mean that muehlfeldi is rather unlikely? and ciureai more likely?

I do not know situation in the Netherlands, but in CZE H. muehlfeldi prefers surroundings of ponds,but I have it from forests, etc. It dislikes dry habitats. But remember, please, that many info to habitat preferences are considering larvae developping. Adults have wings :-) Libor |

There is a large pond nearby. I take your point about larvae and adults. |

It is clearly ciureai. That is a remarkably early record ! Theo |

Thank you both Libor and Theo for the interesting information. The location is De Regulieren, Buurmalsen in the Betuwe The Netherlands.
