A patch with much young Wort rapidly growing but not in flower. Second photo shows the healthy Beetle population can have good biocontrol, wherever enough insects work!

Good to know these have made a start at Umbagong! Thanks for recording them. Rosie, on behalf of the Landcare Group!

Unfortunately the beetles are only partially effective, but any effort on their part is worthwhile.
