Dot Moth Caterpillar

Dear Dara,
Please add WTB? to the the list of people who agree that this is a Dot Moth Caterpillar,
Melanchra persicariae.  According to Wildlife Insight:  “The caterpillars reach 45mm in length and can be various shades of green and brown. The distinguishing features are three pale lines cross the dark prothoracic plate behind the head, the central one being an extension of dorsal line and the eleventh segment is raised dorsally.  The Dot Moth caterpillar feeds on a wide range of herbaceous plants and sallows and can be found during the day on plants such as dock and common nettle.”
