| | | Two from near the River Quoile
I took these photos near the River Quoile, Downpatrick, County Down in July 2007. IDs anyone?
Thanks, John.   |

The first looks like Chrysotoxum bicinctum. Not sure of the second yet.

The longhorn beetle looks familiar but doesn't spring to mind at the moment.
It will almost certainly be in Cerambycidae if you have an hour or so to spare!
Ah ha - to The Coleopterist - how about The Coleopterist - Photo gallery - Leiopus nebulosus  Quote:

The longhorn may be Leiopus nebulosus, the larvae feeding in dead branches of deciduous + occasionally coniferous trees. |

Thanks Paul and Aeshna for the second ID. I looked at the site and it seems to be the one.

Paul | Thanks Paul. Any idea if this is male or female?

C. bicinctum is a female (hoverflies can be sexed by looking at the eyes, which are much more widely-spaced in females). This species is the commonest Chrysotoxum in Ireland. I'd agree with L. nebulosus. The August and October 2007 editions of British Wildlife cover identification of UK longhorn beetles and state only that this species 'has been recorded from Ireland'. It would be worth submitting the record to the Cerambycid recording scheme (Martin Rezjek, email bodo.bodemeyer3atntlworld.com (replacing at with @)

Yes Leiopus nebulosus, a couple of similar Acanthocinini species that can occasionally be confused with it, but this is 100% correct. |

BW Tristan | I'll submit the record as you said. Can I take it from what you have said that this is a rare sighting in N.Ireland?
