green beetles on my cauli
Some of my cauli is coming on great, but some looks like it's been nibbled, perhaps by the infestation of slugs that has decimated nearly everything I've planted this year. The florets have become separated and some seem to be growing faster than others, and they generally look really poor and discoloured. While I was examining them for slugs I've discovered a green beetle-like insect that looks like a cross between a beetle and a cricket and is bright sap green. Is this a pest? Is it causing the damage? I can't find it in any of my gardening books. I'll try and get a photo, but they're very fast & I haven't been able to catch one.
