There are many different types of House Flies with 180 different types estimated to be in Ireland and Britain. When we think of House Fly the first thing that comes to mind is the Bluebottle Calliphora vomitoria, but not all of these flies live around human dwellings and animals. The House Fly Mesembrina meridiana below lives in hedgerows and on the trunks of trees, where they regularly are seen basking in sunshine. As you can see, it is distinctive, with its black body and orange yellow wing bases. The trees in my small wood up the back were covered in these flies over the weekend.
I've been photographing the same fly on my Eucalyptus tree. I took several shots of the flies, all of whom seemed to be "blowing water bubbles" Is this usual behaviour?
