Class IV if mutation. There is some larval lethality (but no embryonic lethality), the majority of mutants die when eclosing: they get their head and legs out and then become stuck. This may be due to the wings sticking to the pupal case. The few that do eclose have severe adult abnormalities, although they are viable and fertile. The two layers of the wing blade are completely separated and the wings appear as haemolymph filled balloons. Halteres are distorted, appearing longer and less rounded than wild type and having a rougher surface. Legs are also misshapen with a kink in the femur. Eye, antenna and mouth parts appear normal. Adult phenotype is enhanced by lower temperature and removal of the Y and suppressed by a mutation of Su(var)205.

Partly viable.
