I noticed small insects in my flower pot that I would like to know more about. They are usually extremely small (1-3mm); slightly resemble either minuscule caterpillars/worms of a greenish-yellowish tint, but the smallest ones resemble moving pieces of hair, grey or translucent - not longer and bigger than a hair clipping from someone shaving a two-day beard.
I tried to capture a yellow one - the biggest one I could find, here (in the middle of the image):
some of the others, smaller ones look like this (sorry for the low quality, I would need a microscope to get a proper image!):
Although they kind of remind me of a horror film ("Body Bags", 1993), I am not particularly scared. But I would nevertheless like to know:
-what these insects are called
-whether or not they are parasites and will hurt the plants
-if they present a danger for humans in general and near food in particular (the flower pot is in the kitchen 60cm away from a fruit cup)
EDIT: The pot was bought at Whole Foods in California, originally had Mint in it. The mint died and I placed poppy seeds in the pot which started to sprout. I also recently tried to plant some fennel I picked in a field, but I don't know at what time these bugs appeared.
