Drents-Friese Woud (there we go again...), the Netherlands. Earl morning (9:30 that is), 2 males hovering on open spot in woodland. Stretch of some 50 meter wide, covered with heath and shrubs. The males were hovering low, about 30 cm above ground, at top level of Calluna plants. They regularly chased each other, but came predictably back. I realize males are difficult, but I hope this is enough to go on! Cor Zonneveld attached the following image:  [58.41Kb] Thanks for your attention Cor Zonneveld |

Please tell me you did collect one. Please Looks like male H. tropica or lundbecki, both would be spectacular. Or the colouration of the eyes is very misleading. Theo |

Sorry, sorry, sorry... However, I have many more photo's. Eye color in live bright green, nicely contrasting with orange on abdomen. New photo's within an hour...I'll focus on the eyes. Thanks for your attention Cor Zonneveld |

Here's the first. Horsefly between me and sun, so sun is shning through. Good impression of what I saw.

OK that helps a lot. Definitely in the montana subgroup for several reasons. It is very early in the year, so lurida, lundbecki and tropica are an option. It is much to orange for lurida. So If you can help looking at the original Are the notopleural lobes brown or orange ? I just can't tell. Is the third antennal segment (without arista !) largely orange or just half dark at the tip ? Theo |

The bulbs at the side of the thorax before the wing base. I can see they are partly orange, partly dark, that troubles me. Theo |

Nono, it isn't, the knobs at the side before the wing base are distinctly orange. Moreover, The apical half of third antennal segment is distinctly dark,. So this guy has all the features of H. tropica. Only known from.....Drenthe. Theo |

You mean, in the Netherlands, I suppose? This was in Friesland...(Appelscha) Is the notopleural lobe not totally covered in hairs? (sorry for my total lack of knowledge...)

Yes, 100 % not lundbecki, so unless there is some very dirty catch, this must be male tropica Theo |
