Tiny fly? In semihydro
 

Help! I have some critters that have taken up residence in my SH pots. What are they? They are so small I cannot get a pic on an iPhone. They have not damaged my plants (Yet?).

I really don't notice them until I water, then they scurry over the pellets mostly inside the pot (pots are clear). They are no bigger than a pinhead, gray in color? They mostly walk, but when they float up to the top of the pot during watering - they will jump or fly small distances. They don't hang out in the plant over the surface.

Definitely NOT fungus gnats - smaller.

So... What are they? Should I care?

Thanks in advance :)

Springtails

That's it! Thank you. And looks like they are happily feeding on algae and no need to worry.

Yesterday night I found this.

Yes, they are springtails, they may damage plants by chewing on the roots and leaves of seedlings. Before few days in my house garden, I found springtails were damaging all plants by chewing them and was just harming to seeds. Then without wasting any time I suddenly called a pest exterminator Brooklyn from Exterminator NYC | Pest Control Services in New York City to exterminate the species. Ever since the exterminator spread pest I didn't face any problem regarding such species.
