The P{IS.LexA.w-}hhIS-lexA hh enhancer trap line was generated by Ernesto Sánchez-Herrero,  using the InSITE system. It was made by replacing the P{IT.GAL4} enhancer trap element in an unpublished hh GAL4 enhancer trap line with a P{IS.LexA.w-} enhancer trap element.
The hh-lexA line used in FBrf0261755, FBrf0236419 and FBrf0254595 corresponds to P{IS.LexA.w-}hhIS-lexA.
