Small White Butterfly Larva turning to Pupa

Observation - Small White Butterfly Larva turning to Pupa - UK and Ireland. Description: I first saw this larva on the side of our wheelie bin, a constant source of wild life. To my astonishment when I checked later it was pupating. Any suggestions please, now I have to try and move it before collection at 7.00 am tomorrow! Photo 1 at 06.2
