They eat over-ripe fruit. So harvest promptly. Jean, who gardened for 30-some years in SoCal and whose peaches never had any problems with the green fruit beetle.

I think you are referring to Japanese beetles, they are stout greenish metallic. Unfortunately,there is no really effective way of dealing with them. Some snip all the buds and blooms off during the beetle season (June and July in my zone) because they ruin them anyway. Pesticides really don't work because they have to ingest it therefore consuming your roses in the process and killing bees and beneficial insects. I (and many here) go out several times per day and knock them off the flowers into a container of soapy water(soap added is the key,otherwise they can swim for days!) You won't get rid of all of them but it will help control the population. Others report milky spore applied to your lawn will decrease numbers by killing the larval stage-grubs, but it takes a couple seasons to see a noticeable difference. Avoid japanese beetle traps sold at retailers, they are reportedly so effective that they attract even more beetles to your yard to munch on your plants.Okay, long response but these are my most hated pest! In short,drown them and get rid of flowers for the short term.

Okay, I'm less bugged out now- no pun intended! last night I woke up out of a dead sleep to my cat freaking out- and this loud whirring in the dark. i heard the thunkthunkthunk of this thing hitting my walls and windows and upon sitting up to inspect the sound, the unidentified and unseen thing flew into my long and sleep-knotted hair causing me to scream like a little girl and run around the room frantic! it was in my hair for damn near a full minute until i got it out!!! What was that thing? My boyfriend, now awake- hid under the covers while i carried on...Was that a small bat? some sort of bird?... I turned on the light to find this beetle- almost an inch long- same description as above! Light green- gold hues... It was pretty- beautiful even- even at 1:30 a.m.... Still, strange and disruptive!! Needless to say, after i got my attacker outside, sleep was restless wondering- How the hell did that thing get in here? and- Are beetles mutating into GIANT almost bird-like creatures? ha!

I don't know what it is but awwww, it looks cute...well, not if it is destroying your plants of course!
