Adults have scute-like bristles and rough eyes. Adults show temperature-sensitive lethality; they die 3-28 days after eclosion at 29oC. There is also a temperature-sensitive semi-lethal period during preimaginal development.
Adults shifted to 29oC shortly after eclosion die 3-28 days after eclosion. Adults have a sc-like phenotype and rough eyes.
The bristle and eye phenotype has not been genetically localised, and could therefore be due to a second-site mutation.
