^*Heat pulses were applied between 72 and 85 h after egg laying. 

^†Heat pulses were applied between 84 and 97 h after egg laying. Large bristles, which are similar in size to ocellar bristles and postvertical bristles, were counted. The wild-type vertex has four such bristles. 

^‡oc¹ larvae were heat treated without crossing to transformants. Similar results were obtained with untreated oc¹ larvae.
