Odonata Specimens

This page will lead you to scanned dragonfly specimens, placed on file primarily for reference. A few specimens are placed here to encourage comments from anyone who has any ideas about them.

The specimens from Ghana were collected during a dragonfly faunal survey by Greg O'Neill, a student at the University of Puget Sound.

Synthemistidae

• Eusynthemis netta, male, Australia, Queensland, Mt. Lewis, 25 Dec. 1998, D. R. Paulson and N. Smith

Libellulidae

• Convergent evolution of dragonfly wing coloration
  Rhyothemis graphiptera from Australia and Celithemis eponina from North America are both in the Libellulidae but are not especially closely related. The similarity in wing coloration is entirely a case of convergent evolution, and the function of these brightly colored wings is unknown. Speculation of mimicry of distasteful danaine butterflies (including the Monarch in North America) may be warranted.
• Libellula luctuosa, female, Oregon, Jackson Co., Tou Velle State Park, 7 mi. N Medford, 2 Aug. 1998
  This specimen, collected in Oregon by Jim Johnson, is quite aberrant in wing color but is still thought to be that species. Not only that, but it is a very small individual, with a total length of 40 mm and a hindwing length of 28 mm. Is this a developmental anomaly?
• Orthetrum julia, male, Ghana, Central Region, Kakum National Park, 27 Aug. 1997 (HW 31)
• Trithemis dejouxi, male, Ghana, Brong Ahafo Region, Bui National Park, Djiapoli stream, 19 June 97 (HW 29)
