Stereomicrograph: Fabrice Parais of DIREN Basse-Normandie
I'm a big fan of Nikon Small World, an annual photomicrography competition (featured before on Neatorama in 2007 and 2008). The winners of the 2009 contest have just been announced.
I particularly like this one above, the Atherix ibis (watersnipe fly) aquatic larva magnified 25x by Fabrice Parais of DIREN Basse-Normandie in Hérouville-Saint-Clair, France.
