According to the guide page, adults in this family can be up to 5 mm long, so I feel good about this ID.

Heliopsis-mining fly larvae
The dots in the un-mined portion of the leaf shown in this photo look like the feeding punctures a female agromyzid makes with her ovipositor, so it would seem that these are agromyzid larvae. 4 mm seems large for them, but I don't know how big the biggest species are. The only agromyzid listed in Spencer & Steyskal (1986) with this host is a flower feeder. I hope you are able to find these again and rear them.

 
Thanks
for the ecological information. That is great!
I no longer live where these were found but I still have lots of the host plant so maybe. I well know; sometimes these things take a long time.
