For as far as I know (and could find in the insects book) this is just a simple house fly, or Musca domestica.

This shot was taken the same day as the Ladybird which I posted a few days ago. Next time I'll try to get some more depth of field.

PS: A few days ago, I've moved this site to another hosting provider due to continuing server problems at my previous provider. Also, as I'm very busy graduating, I'm not able to update this site as often as I'd like to. But you might have noticed that already. :)
