As this is rare species I would like expert opinion on the id - preferable from BWARS - so no enthusiastic ameteurs please

Species interactions

No interactions present.

I would trust a few of the as you call them enthusiastic amateurs I think your comment is rather harsh as some of them are very knowledgeable.

I didn't mean to offend

I didn't mean to offend anyone but as it a species of conservation concern I would like expert advise and as BWARS and Hymettus ask people to post on this site I did so

I can understand exactly what you meant by your comment, and would hope that no one takes offence (although I agree that it could be taken as being a bit harsh).

I would think that opinions from anyone who feels they know the species, and potential confusion species, well enough might help - as long as they explain their opinions with a comment rather than just clicking on "agree".
In general I would consider this to be the best way forward for any identifications that could potentially be controversial, or involve difficult species pairs/groups. Simply clicking on an agreement is fine when an ID is straightforward though, unless the original poster (or someone else) has specifically asked for ID pointers or other information.

I can't help with the ID though, I'll leave that to those who can (most of whom will probably be "enthusiastic amateurs" - some enthusiastic enough to hold volunteer positions in groups like BWARS!) ;o)

Formica exsecta

BWARS is fully amateur and enthusiastic!

The chances of this being Formica exsecta are extremely remote as there is only a single known extant English population, located on the Bovey/Chudleigh heathland complex in south Devon.

The most likely candidates from Bournemouth are Formica rufa and F. sanguinea, but to be absolutely certain, it is essential to have a specimen or two to check under the microscope. WE have some black-belt ant folks within the Society, and I am sure that one would be very happy to look at any you grab.

Thanks Stuart Sorry for my

Thanks Stuart

Sorry for my ill choosen words - I meant non-expert rather than none professional.

I know that f. exsecta is very unlikely but they were here and having seen f. rufibarbis in the most unlikely of places (a road verge) I thought I should check - especially as there is no obvious nest and they don't look or act like sanginea.

I'll grab a couple in the next few days

Thanks again

The specimens you sent reached me safely, I'll have a look at them this evening

is really great - the ant is carrying the forceps (back part) of an earwig, and it looks like the ant has massive jaws
