    Are they round or flat? Was the tree alive? If not has it been dead for a long while?

    My initial thought is they look flat, and if the tree was not dead for more than a year, I'd guess they are one of the Agrilus borers. Here are 2 that feed on walnut (but there are others...):

    If that ia the case, they'd have to get them to adult for positive identification (that goes for most larvae...).

    If they are round, and in dead wood buzz sawyer gave a possibility, but again there are others... Outside from a few, larvae are hard to get too specific without more information. Often the best anybody can do is narrow down to genus.

    I will pop one out and get a better photo tonight.... I believe they are round...yes the walnut was cut down 1-2 years ago.... the reason I asked is because these are in the hickory I got this year too (don't know if they are same bug or not)... and it hasn't been cut down for over 3-6 months...I think they are the same but I will check in a piece of hickory, ash, and walnut tonight....

    In my hickory pile you can see little piles of saw dust that these little bastards leave behind...

    Thanks for the quick reply guys!!!!

    Leads me to think its more of a "deeper and dead wood" type if they're still active in a wood pile. How deep into the wood do the galleries go?

    Throw a piece or two into a plastic bag and see if they emerge as an adult next spring. If they needed a living tree, they may not, but why not give it a try.

    Send one to an entomologist or extension agent.

    Pretty sure they will want one alive enough that they can rear it to adulthood....

    I want a live one to eat so I can gain its powers.
    Put it in a jar with a chunk of wood and some moss so as to better replicate its natural habitat.
