Lurking lizard nets nothing

The stealthy hunter has a problem on his hands er, pads.  The lurking lizard is stalking the insect that can just barely be seen on the right (the black triangle).  Problem is, the lizard is on the other side of the netting and he can't figure that out.  I watched the scene play out for about 20 minutes.  The insect would move every once in a while, but never fly away. The lizard's best lurking did him no good for his breakfast this day, though I suspect the practice was very valuable.
