I just got some native black walnut from near Van Cleve, Ms. last week and I quartered a log and cut one section down to call size and it looks like an ambrosia beetle discolored it. I have never run into this in Walnut. I have run into a lot of worm holes but not the discoloration associated with the ambrosia beetle. Have any of you run into this. This one teamed with with a piece of ambrosia maple that Tom Crook sent me will make one striking call. Look forward to your feed back.
