'Striking' black and white insect

'Striking' black and white insect

Observation - 'Striking' black and white insect - UK and Ireland. Description: I spotted this 'chunky', black and white insect (1.0 - 1.5 mm) whilst walking along a woodland track. I wasn't sure what it was, but one of my field guides has a picture of a sawfly, Zeraea fasciata, which looks very like this.
