Experts say a mini heatwave in the coming days will see the massive moths heading to our shores. Wildlife lovers are being encouraged to take a 'torchlight safari' after dark over the rest of this week and look out for some of the giant moths currently on the wing. Some of the striking autumn moths that have been spotted across the UK this week include the Silver-striped Hawk-moth, the beaked Hummingbird Hawk-moth, and the Convolvulus Hawk-moth - which has a wing span of over 10cm. And according to the Butterfly Conservation, the influx of rare moths from continental Europe this year are being drawn to the UK by unusually warm weather expected from the south.
