The Painted Lady Butterfly and Humming-bird Hawk-moth arrive from Africa and becoming increasingly common in the UK. To find out just how common, we need your help.
This online survey specifically targets two amazing migrant insects which come to Britain from North Africa and the southern Mediterranean each year and are often seen in gardens: the Humming-bird Hawk-moth and the Painted Lady butterfly.
Numbers of both species appear to be increasing, probably as a result of climate change common, and the Humming-bird Hawk-moth is beginning to survive our warmer winters.
Many mysteries remain to be solved about insect migration - we do not know, for example, whether the British 'born' offspring of these insects migrate southwards to avoid the winter here. With your help, we will track the arrival, spread and possible departure of these two beautiful and exciting species during 2015.
If you see one of these amazing animals during 2015, please log your sighting using the simple online survey.
