There was an error published in J. Cell Sci.119, 2935-2944.

In the Materials and Methods section, the incorrect light intensities were given. The correct intensities are shown below.

Flies were placed under a white light source (Lambda LS 175W Xenon-arc lamp with 400-700 nm bandpass filter, Sutter Instruments, Novato, CA, or equivalent), at ∼2297 lux for stage one TRPL translocation (unless otherwise indicated in figure legend) or ∼244 lux for stage two.

The authors apologize for this error.
