sooby- It is a money tree (pachira aquatica). There are actually a couple of curious deformed leaves on the plant, so that was my clue to put the potato on the soil, to check. I cannot sayat this point if they are actually related (leaves to bugs). The rest of the leaves look great.
These bugs are so small a photo would be a challenge, but I'm up for it. Lastnight, when I removed the potato from the stop of the soil, I could see a skinny speck of dirt crawl across the potato without the magnifying glass. Only when I used the magnifier, could I see that they are irridescent/silvery, long and skinny, and they do have antennae they move back and forth while crawling. They're hunting for food.
I actually saw one start chewing on the potato itself.
I've already sprayed the plant over, under and top of soil, but I can check again with the potato wedged in a little further and see if I can get a photo with the good lens. I'll include a photo of the leaf too.
