What are these mystery spots?

Mystery spots


Here’s the scenario: After careful analysis, we realize these spots are on everything: ground, garden decor, all plants on the west side of the yard. These are all understory plants under our huge shingle oaks and the neighbors’ big sweet gum that hangs over. The “things” don’t appear to be damaging anything at this point and the plants are all healthy. Our concern is what might burst forth from these “spots” in the future and take over the earth! At the nursery the guys operated on one — cut it in half and looked under the magnifying glass. They thought it most likely was an egg for something but couldn’t tell. - Betty Lou -

    This looks like frass from some insect; I’d guess some type of caterpillar. You might get some binoculars and see what you can find up in the shingle oaks and sweetgum. I would wash the stuff off of the garden decor.

    The good news is that the spots will probably not burst and take over the earth. What a relief!
