they look like thrips to me, seeing the "mama" fly may just have been a coincidence
Thrips
Thrips are really tiny, but can be seen by the naked eye. Some may have wings and some may not. Thrips reproduce rapidly, especially in tight places. That is what makes them hard to get rid of when using pesticides. The suck the sap right out of your plant with there piercing mouths, which makes the leaves look like they turned white. You can tell when you have thrips by taking a look at your leaves, the leaves will look as if there chlorophyll have been ripped right off the plant. Plants that are damaged can’t be healed thus making it harder for the plant to absorb light. SO if left untreated the thrips will kill the plants. Damage also can be seen by the greenish black specks of there poop they leave on leaves. Also the plants will show silver patches from scar tissue. Depending on the severity at first, thrip damage might look like spider mite damage until it increases in damage and then thrips case is for sure when you see the greenness replace with big parts of white.
One good way to repel thrips for those growing outside is to use garlic, this is a good way to keep them away before you get them. The color yellow attracts the thrips and should be advised not to have this color around your grow.. If you already have them using neem oil, and or lady bugs can get rid of them. If the infestation is bad then you need to use biological solution like, pyrethrin-like insecticides. Picture 8 shows thrips damage.
