Scarab beetles return

This is a story about the green scarab beetle (Diphucephala colaspidoides). This beetle occurs in south-eastern Australia including the Grampians region where I live, and the beetles usually feed on native foliage such as tea-tree, melaleuca and wattles.

Back in 2006 these beetles caused damage to grapevines, rose bushes and fruit trees in this region, something they rarely do here.  Why was the spring of 2006 different? And why do these beetles swarm sometimes? These questions and more are answered in this video.

As usual please drop me a comment if you like the video. Thanks for watching!
