Possible grape flea beetle larvae I.D.

First id like to say this site is great i am a new comer to permacuture and very passionate about it. I have found this site very helpful and am happy to be a member. That said on one of my daily walks observing the property i came across this little guy on the native grape vines in the yard. I took a pic and attached it.

My questions are
1. Does anyone know what it is.

2. Is it a threat to anything else i may be growing.

3. if it is a threat what would be a good way to minimize the damage done.


I am in south eastern michigan by the way.

Might be Grape Flea Beetle larvae. I wouldn't worry about it, personally. There can be a bazillion critters out in the world but relatively few of them will bother the garden and even fewer will bother the healthy garden. In the spring our native trees are literally dripping with caterpillars of all sorts, few seem to care about the garden.

IF you can see it and catch it and it is doing damage..you can hand pick it. Permaculture doesn't mean to allow something you can remove to destroy your harvest..just don't bring in sprays..but you can pick pests if you see them...esp before they lay eggs

I can see it and managing it by hand would be a possibility there are many of these bugs on a plant that isnt really part of my managed area more of my zone 5 border on a 3/4 acre urban lot. While they are eating the hell out of the grape leaves i was more worried about them becoming invasive with any other plants. Last year the leaves on the grapes did not look very healthy at all they had white bumps all over they and didnt look healthy at all. So not sure as to if that may be the reason for the presence of the bugs this year cause they werent there last year. as of right now there is no signs of them migrating to anything else. I recently planted siberian kiwi so that is a primary concern when it comes to this problem. they are some distance away from the grapes but still a concern.

So upon further investigation it does in fact appear to be bettle flea. and the bumps from previous year appear to have been an aphid problem. The beetle flea problem is a bit out of control on the grapes so i guess i have to onitor the rest of the plants to make sure it doesnt spread. thank you all for the help.
