With the hot humid weather the bugs are out in force especially this type:
They are called Vegetable grasshoppers - binomial name is : Atractomorpha similis or A. australis.

Although they aren't considered major pests they have been having a good feed on the silverbeet :
So action was needed. I tried Neem several times - it had no noticeable effect on them. So off to the Hardware store for other options and I purchased a garlic/onion/pyrethrin trigger spray and another one that was straight pyrethrin based. The former seems to have knocked them back quite a lot even with one spraying.
The silverbeet struggles here over summer but I have seen some from other gardeners that puts mine to shame, so that is a stimulus to "try harder"
