Black bugs

[Libbie]

I've found a few tiny black bugs in my crested geckos food bowl, they are tiny black bugs that jump, what are they!?

 

[Aimless]

probably these guys. a little smaller than fruit flies?

Phoridae - Wikipedia, the free encyclopedia

Phoridae look like they have wings, these things I can see don't have wings, I'm quite worried as to what they are, they look like tiny fleas, thanks

Google images for black springtails. You could leave the 'black' off to get pictures of other colours, some grey ones look black in the right light.

Yes they look a lot like those springtails. Are they harmful!?
