Mystery mine on Lantana

Another commonly observed mystery leafminer that I'm hoping someone can collect and rear: An Ophiomyia species (Agromyzidae) that forms winding linear mines on Lantana camara, L. x hybrida, and maybe other Lantana spp., in California, Texas, Mississippi, Alabama, and Florida. The well-known species O. camarae makes a mine based on the midrib, with short extensions into the blade along either side:

The mystery mines are not based on the midrib, although they sometimes have similar short branches where they encounter lateral veins. It's conceivable that they are made by the same species, but adults need to be reared to confirm this.

Thank you for the note. I’ve not seen this leafminer in SD, but will have have it on my radar for now.

I don't know if we will be back in Carlsbad this year, as Ed's mother, who lived in Carlsbad, passed away. I still have friends in Encinitas, and it would be nice to see them, but I don't know if that will happen.

One mystery solved! Owen Lonsdale examined the specimens reared by @sessilefielder (male shown here) and determined them to be O. camarae, so it looks like this species just has a much more variable leaf mine than the literature lets on. It still seems a little odd to me that most (all?) of the examples in California are of this type, but it certainly simplifies identification, given that there were some intermediate examples.

Thanks for following up.
