[Odonata-l] Hine's Emerald

[Jones, Colin (MNR)]

Hi Andy et al.,
 
The newly discovered Hine's Emerald site in Ontario is actually south of many of the other sites in the U.S. I strongly believe that this population has probably been there for a very long time but has simply been overlooked in the past. There are certainly other species of Odonata here in Ontario, however, that do appear to be shifting their range northward including Pachydiplax longipennis, Perithemis tenera and Celithemis eponina.
 
All the best,
 
Colin Jones

Just a thought, but given the general Northward movement of insects in
response to climate change, how do we know that they've been there all the
time, and not simply moved into the region in the last few years? Certainly
here in the UK we've been getting a new species every two years since the
mid 90's, all moving in from southern Europe.
