Each one of those spots looks just like the beginning of leaf miner's cycle. Fly deposits one egg via pointy oviduct through the top of the leaf. That causes the yellow spots. When the egg hatches to a larvae, then you'll see the reason they are called leaf miners. Skeletonizers. Could you try slicing open one or two more of those tiny lumps? Use a good magnifying glass, metal pointer, and poke around more. I'll think about these other possibilities. I'll be back... | |

I've done some additional shots. The lightning was diffuse due to rain, so the bright spots on the backside look like they have zero relief. Overall, the height of those spots is reaaaly small. Also, near the end of images I tried to cut one open, and there is nothing inside. | |

Hey, I could be wrong, this is tough trying to put one's neck out there over a photograph! Regular soil in NOT to be used for anything sequestered from the large body of soil...pots have to have sterilized potting soil. Otherwise, for instance, you could get a disease or insect yet have absolutely no beneficials to monitor this chunk of soil. Potting soil, order off the internet. Or plant these guys in your garden. Whenever you bring exotic soil or plants... | |

Unfortunately the lights are just too bad to take a decent close up photoshoot, so I will have to update this post tomorrow morning. I am gonna make a decent macro shoot of an leaf with a open packed. Great tips regarding raw cloth. Actually, I am just using regular soil from the garden and coco fibers. I think the soil had some manure horse mixed in last autumn. | |
