      Blue light illumination of flies expressing Crei\ChR2Scer\UAS.cUa.T:Avic\GFP-YFP under the control of Scer\GAL4Foma1 (in a norpA36 background to eliminate any photoreceptor mediated visual responses) produces an escape response which is behaviourally similar to that induced by looming stimuli in wild-type flies, with 90% of flies raising their wings prior to takeoff. Expression under the control of either Scer\GAL4Tab2-201Y or Scer\GAL421D does not induce an escape response upon blue light illumination.
