DSCN5935 odd 'caterpillar' in straw

Observation - DSCN5935 odd 'caterpillar' in straw - UK and Ireland. Description: kids found this in straw as they were making scarecrows, not entirely sure it's a caterpillar as it was tapered toward one end and flicked about more like when a sawfly larva is disturbed, interesting markings
