Another compartment border in the wing?

This article arose from a paper in Scientific Reports by Abbasi and Marcus that presented evidence for a previously undiscovered lineage compartment in the fly wing. In our little article we question the existence of this border and present new counterevidence.

We have an interest in the situation in butterflies, but not the necessary expertise.
