And what happens when you don't check your Savoy cabbage for three days due to it raining and a she'll be right attitude, because you think what can go wrong in the garden while it's raining liquid gold, right.
Simple, let 10 or so white cabbage moth grubs loose on your savoy cabbage.They blitzed it, seem to like the savoy around here, it's copping a hiding compared to all the rest I have planted.
There are many types of caterpillars which are usually the larval (caterpillar of a grub) stage of moths such as cabbage moth (Plutella xylostella)and small cabbage white butterfly (Pieris rapae). Cabbage white butterfly is white with distinct black spots on the wings and is around 40mm across. The cabbage moth is greyish and small and is around 10mm across. The moths and butterflies lay their eggs on the underside of leaves. The larvae of caterpillars hatch from the eggs and then feed on the leaves or fruit, so it’s the caterpillar of the cabbage white butterfly or cabbage moth which does the damage. The blue-green smooth textured caterpillar is that of the cabbage white butterfly, while the caterpillar which is green-brown is that of the cabbage moth. They both start eating the outer leaves before moving to the inner heart of the cabbage. It is a good idea to try and either pick off the caterpillars or spray them when they are still on the outside of the leaf, before they tunnel into the heart. Plants favoured by cabbage moth and cabbage white butterfly include cabbage, broccoli, Brussel sprouts, Chinese cabbage, celery, beetroot, rocket and watercress.
