Like the imported Pieris rapae , the dinero looper is small and green . The larva of the nocturnal chocolate-brown moth , it pay back its name from the direction it make a motion , arc its back like an inchworm , creating a loop-the-loop of sorts , and pulling itself forward .
Although green like the cabbageworm , the looper is slightly larger — about 1½ to 2 inch long — with white stripes down its back . incite relatively chop-chop , the looper feed on the undersurface of brassica leave , taking large bite as it goes .

Other predator that feed on looper nut and young larvae will also cluster to the nectar and pollen plants . go under away some ground or a few pocket-sized weed specifically for this function . Plant a lot of these attractant plant , and sow them in succession so they ’re always flower when you need protection .
