[Odonata-l] Combat between anisopteran protagonists

[ben@e-3d.co.uk]

Hi
I'm trying to learn more about dragonfly combat, and would be grateful if
someone could point me towards a suitable authority or document(s).I'm looking
for information on actual physical combat between dragonflies rather than the
threatening displays or flying skill demonstrations that can occur between
conspecific dragonflies.

Thanks
