I have searched on the internet but was not able to find what this is, I first thought it was a kind of dragonfly, however there are only two wings which is not usual for a dragonfly. Any suggestions what this is?
Neuropterans have large lateral compound eyes, four wings and a generalised pattern of veins.
Identifying morphological features:
Soft-bodied insects with copper-colored eyes, long thread-like antennae, and lacy wings.
Most species are green, but some are brown, especially overwintering adults of certain species
( Reference: Bugguide )
A similar family of lacewing, Hemerobiidae also exists which are brown, have rounded smaller wings and found throughout the world.
Here's a link to wikipedia showing the phylogeny of the Neuroptera as explored using mitochondrial DNA sequences: link .
