Reed Dagger is quite a scarce plain brown moth that thrives in the phragmites that fringes the trails. The adults lay their eggs within the stems of the plant and in early September we start to see the caterpillars out on the boardwalks. By this time they are are quite big and seem to think that they are impervious to any threats... however they are a favourite snack of juvenile Cuckoos but I reckon that they should now be save with their enemies safely on the way to Africa!
So all they have to look out for now is big human feet not looking where they are going!
