Unusual Landing Spot - _TNY_4915

This was a bit of a surprise combo found in Åva-Stensjödal in Tyresta National Park just south of Stockholm, Sweden.

 

I was in the middle of trying to get some good shots of the legless lizard known as the slow worm (Anguis fragilis) which I came across on the gravel path.

 

Then an alderfly (Sialis sp.) came flying, wanted to land and decided that the glasslike body of the slow worm was the best spot!

 

Right after taking this shot the lizard decided to start moving and the alderfly, facing away from the head of it, did the same, reulting in the alderfly briefly staying in the same place while the slow worm moved, creating some weird zoological moonwalk effect.

 

There are five species of alderfly in Sweden and identifying which one typically requires study of genitalia, so this one will stay as Sialis sp.
