sianhilton: Dorset coast small ant (23. Feb 2008 14:28)

A few years back while walking along the cliffs of Dorset, I noticed a stream of small redish brown ants. These ants were fairly small around 3-3.5mm and were streaming in file of about 3-4 thick from one nest hole in to another at fairly rapid rate.

If I had to guess at a species it would be Tetramorium Impurium?

Any plausible guestimates?

i think it may be many species

sianhilton: (23. Feb 2008 15:51)

I think the number of possible species it could be are limited based on the description and the fact it was in the uk

well maybe lasius flavus but i doubt it as they stay underground but maybe...

Hi Ashhad 1

They were definitely not Lasius Flavus.

Thanks anyway

Sounds something like Tetramorium caespitum, but I don't think that Tetramorium impurium is native to Britain.

there are only about 42 species in the UK, so it shuldnt be hard to identify them, however red 3.5mm doesnt help much lol

got any pics?

sianhilton: (24. Feb 2008 17:36)

Sorry no pictures
Will be better prepared next time!

Although there are 42 species

These were redish brown, 3-3.5mm apprx, I would guess from what I saw the population was large. This would narrow it down some what.

I agree with Phasmid these may have been Tetramorium Caespitum

Could be, but still hard to say without pictures. Even with pictures it difficult sometimes. ;)

Tetramorium are more black-brown, than red-brown. Can you recognize any other features, are they of Formicinae or Myrmicinae family? If they are Formicinae, red-black, small and very numerous, I would say it is Lasius emarginatus, but I don't know if they live in England. Check the photos:

It may be something else, of course, but if you see an unknown ant it's good to compare it to well-known species and tell which one looks similar
