The caterpillar is stocky, grey to reddish coloured, provided with many point warts as well as some short hair and shows a bright, interrupted back line. The stigma are bordered black and white. The front part tapers towards the small head. The caterpillars preferably feed on various herbaceous plants including Plantago major.[2]
