Anax parthenope (Lesser Emperor)

Slightly smaller than A. imperator (Blue Emperor/Emperor Dragonfly) and with a brown thorax as opposed to a bright green thorax. The blue ‘saddle’ at S2 tends to stand out prominently, particularly on the male, though beware the male A. ephippiger (Vagrant Emperor), also with a blue saddle though somewhat smaller. The female looks similar but we’ve yet to see one.

This now seems to be an annual migrant to Britain and has, supposedly, bred in Cornwall. I’m not sure I’d go with resident, personally, though it does feature in our resident lists.

Id Notes

  • Brownish thorax and S1
  • Narrow yellow band at base of S2
  • Largely blue S2&3 (♂)
  • Yellow costa
