      Reference

      Sectors of ommatidia replaced by chitin and bristles; lower half of head also reduced at 25oC. Lower half of eye apparently produced from fewer than the normal nine or ten presumptive ommatidium-producing cells. Temperature-sensitive period for ommatidium formation first and second instars; third instar as well for head reduction.
