Naughty Caterpillar

Observation - Naughty Caterpillar - UK and Ireland. Description: My nasturtiums now have no leaves or flowers left at all due to a gang of these pesky caterpillars! I'd like to know what they are so I can at least comfort myself that the garden will instead be full of wonderful butterflies/moths!
