Aphids are sentinels of climate change, researchers have shown. One of the UK's most damaging aphids -- the peach-potato aphid (Myzus persicae) -- has been found to be flying two weeks earlier for every 1°C rise in mean temperature for January and February combined.

This year, the first aphid was caught on April 25, almost four weeks ahead of the 42-year average.
