This lacewing was sitting in the deep shade under a tree – not ideal conditions for photography!

I found a great site for the identification of Japanese lacewings: site here.
I read some interesting information about the use of lacewing larvae in biological pest control (they eat aphids): info here.
Also, this Wikipedia article about lacewings is fascinating: article here.
