  @BobTheGardener that seems to only affect dry beans

  Yes, you normally see the evidence later, when they burrow out of the dried bean, but the grubs burrow into the beans while they are still young and green so could cause secondary infections, which is what that looks like.  Open some of the affected beans and see if you can find any grubs.
