Knot Grass caterpillar

Observation - Knot Grass caterpillar. Description: I think this is a Knot grass caterpillar (Acronicta rumicis) feeding on my Rosy cushion interall. What I found most fascinating was that the caterpillar's faeces were pink (I assume from eating the rose), and this is not something I have seen before.
