Lacewing

(Photo:  Simon Harding)

Simon photographed this green lacewing (Chrysopa perla) at Filnore Woods.  It is probably hunting for aphids, its main food supply.  The larvae are also voracious gobblers of aphids so the female lacewing usally lays her eggs near an aphid colony.

The body is green with a row of black squares on the underside and the blue-green wings have a lacy network of black veins.

Check out Chrysopa perla on wikipedia, where there is a tremendous video of a lacewing searching for aphids and snacking on some flower nectar for afters.
