There was an error published in Development139, 3849-3858.

Fig. 4B incorrectly showed an image of an apGal4>UAS-hWIF1 wing disc instead of an apGal4>NTDm-WDHs-EGFDm wing disc. The correct figure is shown below.

As both genotypes display a very similar disc phenotype, this error does not change the conclusions of the paper.

The authors apologise to readers for this mistake.
