These micro bats were hanging from the roof of the tube. They were only ever described to us as microbats but I now know that this is the generic name given to a number of small species of bats that feed on insects etc. So I don't really know sort of bats these are.
You're game to get amongst them - I would be afraid one would get in my hair. We had a bat in the house recently and I rang my husband who was working in Fiji and demanded he get on a plane to come home and deal with it. Tense night!!
