There was an old woman who swallowed a fly.

It seems as a species we still have not learnt our lesson: it is a bad idea to interfeer with other species. I was reading this article from the BBC about the Harlequin Ladybird; unlike native numerous British species of Ladybird, this one seems to have been introduced from Asia to Europe as a means of controling pests like Aphids. Being particularly invasive, significant concern has been raised about its spread. Scientists are putatively considering introducing a mite which will disrupt the invader’s reproductive cycle. Did these people never hear the rhyme when they were young… “she swallowed the spider to catch the fly”. This kind of behaviour will only end up with us swallowing the environmental equivalent of a horse. And the public is expected to accept the release of genetically modified species into the wild.
