Tiny flies

This tiny pair of flies were "sitting"  on an osteospermum petal - which gives you an idea of just how small they are.

Their scientific name is Neotephritis finalis -  they are a type of fruit fly.  Unfortunately, the activity being witnessed here will in due course result in the production of sunflower seed maggots, which cause damage to some fruit crops.  

I hesitate to say that there is more detail in the large view - but there is if you're up for it.
