For about a week I have been experiencing more of the little black flies in The Cottage than I have done before. I had always just assumed that they were ‘fruit flies’ but had no real evidence to support that because to the human eye they are just tiny black irritants. Then a couple of days ago I decided to try and photograph one that was walking about on the bathroom mirror. Have you ever tried to photograph a moving 3mm creature using the available light from a household bulb? It’s not easy I can assure you. Then this evening for the second evening running I found one in my wine – actually yesterday there were so may it got tipped out instantly. Tonight I had the presence of mind to photograph it first. Then, as the fly could have been there for quite a while, I tipped it out. This was getting serious! So now I had a clear enough picture for identification. They are called Vinegar Flies (Drosophilidae) and are attracted to the smell of fermenting fruit and other plants. There are about 2900 species of Vinegar Fly known worldwide (at least 17 in New Zealand) and have taught us most of what we know about genetics. Fruit flies (Tephritidae), on the other hand, are not found in New Zealand.
There you are, Pauline, I did manage to blog on the little creatures. Wasn’t that interesting? I bet you can’t wait for the next one.
