A Katydid (Pterophylla camellifolia) as shot by my wife last weekend with her Nikon Coolpix P100. They emit a sort of chirp and man, they're NOISY at night. They usually keep at it en masse until about 3AM when they knock off and go to sleep.
Even more Dragonflies. Note the difference in colours of the compound eye in the last two images. The last one has red patch on the compound eye, while the first three do not.
