Sympetrum striolatum

Looks like Common Darter to me. did the odonata sp have a waisted abdomen?

Shame to say...

...I'd have to agree it's a male Common Darter. They can attain quite a reddish colour but the Ruddys are REALLY red. Once you've seen one in good light you know the difference! And yes, a top view showing the waisted abdomen is also a massive help with positive ID of the Ruddy.

BecclesNature & Vinny are correct

This is a male Common Darter. The legs are the best feature to use to distinquish Ruddy and Common Darters - but beware late in the summer because the legs of old Common Darters can become very dark, making the yellow stripe much more difficult to see.
Two prominent yellow stripes on the side of the thorax is another good indication that it is a Common Darter (this feature can cause confusion in young or old individuals though!).
