I first thought this was Pales pavida but it doesn't have the reddish tip to its scutellum. Is it Epicampocera succinata?

Hairy eyes and a projecting mouth edge? Should be Eurithia anthophila  It looks a bit too big for Epicampocera.EDIT: Epicampocera are quite dark-blue but the relative proportions of head to body are different too.

Where is it from ? It is Eurithia, but not anthophila: the vertex is too narrow and the palpus is yellow, suggesting Eu. vivida, the most bluish Eurithia in my experience. Theo |

Very interesting record if it is E.vivida - they're rare as hen's teeth in the UK

is it from the UK and are we very VERY sure (too paraphrase the Spice Girls) that the pictures concern the same specimen ?? Theo |

Wow! Thanks Chris and Theo! I took the photos in The Wilderness, a wooded area in Reading University grounds, Reading, UK, on 2010-07-30. On Google maps: http://maps.googl...h&z=17 I am confident that both of the above photos were of the same specimen. Looking back at my original records, I find that I have a sequence of 8 contiguous photos of this specimen, including the above two, with times of 10h51m or 10h52m. I then have a few photos of other insects, followed by 4 contiguous photos of something very similar or identical the above specimen with times of 10h55m or 10h56m. The following photo is the first of the sequence of 8: tristram attached the following image:  [174.26Kb] |

Well, there is no way to be sure which species this is. In the first pic, the palpus is yellow, so it seems, in the last it is definitely dark, suggesting connivens rather than vivida. Moreover, the last pic clearly shows 4 post DC, the apparent 3 post DC from the first pic is misleading. Time and locality support connivens. So with the new information I'd favour connivens. Still I guess connivens is pretty good as well. Theo |

E.connivens would be typical for this part of the country - I get plenty each year usually

The following photo is the last of the sequence of 4, so it might not be the same specimen and the above. (The rest of my photos were more blurred).

Well, it is definitely Eurithia but the male genitalia are usually retracted too much to male out anything ... here we really need a specimen
