      Statement
      Reference

      11% of expected mutant embryos hatch as first instar larvae. The latest observed stage of mutants is adult. Nerve cord length is 82% of embryo length. Midline guidance failure of repellence phenotype, evidenced by midline crossing, is mild.

      sliF81 and sliF119 are probably the result of the same insertion event.
