How do I control these bright green lady beetles that are eating the leaves on my LillyPillys?

This insect looks very much like a juvenile leaf eating beetle. As we don't have any products in our range that are registered for this purpose, the best advice we can provide for control is to use a hand removal method. This is best done in the late afternoon when the beetles are not as fast moving. Get a bucket of soapy water handy place underneath the trees branches. Shake the branch to remove any of the beetles and drop them into the bucket of water.
