Stream Bluet vs. American Rubyspot

Here is an odd damselfly behavior that Scott K. and I observed last July. I was excited to list my first American Rubyspot, the damselfly on the right, which I blogged about on 21 July. The rubyspot faced two Stream Bluets (see 3 August post). The later odonate is common across much of eastern North America. Scott and I were surprised when the rubyspot arched its abdomen in what appeared to be an aggressive behavior. Was this action in response to the bluets?  Or was another rubyspot in the vicinity?
