I find that they don't squash, no matter how hard you hit them they fall to the ground, shake their heads and stagger around for a minute or two then fly off in search of more blood. Hard or what! Tim |

The first one is a male of pluvialis / subcylindrica. The second one is more difficult, from the pic it might be crassicornis, however, time of year suggests otherwise. I would need more/better pictures of the antenna Theo |

Thanks Theo, and I give way to your vastly greater knowledge. Now, I'm just wondering where I went wrong with the key in Stubbs & Drake: I can't see any orange on antennal seg. 3; and there doesn't appear to be any orange at the side of tergite 2 and 3. So, following the key this must be either crassicornis or italica. here's an enlarged photo of head/antenna - probably not detailed enough though. tim worfolk attached the following image:  [79.03Kb] |

And here's the only shot I got of the dorsal side - strong wind so very shaky. Thanks Tim tim worfolk attached the following image:  [100.15Kb] |
