Deep in the gloom of a conifer wood today, a foul odor of rotting flesh led me to a Stinkhorn fungi -Phallus impudicus. Flies were being attracted by the smell and were visiting the sticky gleba where the spoors are held, thus helping to transport them. Evolution in action. One small Diptera had blood red eyes and a striped body. Anybody know this U.K species?
Those smaller flies on the Stinkhorn with the red-eyes,orange thorax and striped abdomen are Fruit-flies of the genus Drosophila. They are probably D. melanogaster. This type of Fruit Fly is also a pest of homes and restaurants.
