Two questions and the obligatory phots

First day this year with the Nikkor 60mm Micro and caught these on a Arizona Poppy.
Question 1. I pushed and pulled, cropped and filtered, denoised and sharpened and got this 2x2" image. Does this qualify as a "macro image"?
Question 2. Does anyone know what they are?

The picture looks way over-processed. Could be thrips (small insects that scamper around on flowers. Some drink sap, others are predatory).
Adults have wings and they look like this: https://bugguide.net/node/view/99458

It's only macro if the subject is 1:1 or less on the sensor. That is, the subject must be the same size as, or smaller than, the sensor, otherwise it's a close up.

I found a way to answer that question for any camera.
Find the size of the sensor?
Let us say 35mm in width.
Shoot a picture of a metric ruler.
If you get a 35mm of the ruler, that is 1:1, or just macro. If 17mm seen, 2:1, or doubled, 12mm, 3:1, and so forth.
Picture shot with T2I and a reversed lens and tubes. Sensor width is 22.5mm. So the shot is 4.5x.
