A NEW SPECIES ADDED TO CA RECORDS 5-99!

Distribution Maps are maintained by Tim Manolis. They are based on information originally collected by Dennis Paulson (see address below) and they are now being updated by new sightings and specimens found in museum collections. If you find a species in a new county please contact Kathy and/or Tim.

This site was begun in 1997 because of my frustrations in trying to identify the damselflies that came to visit our garden pond. I discovered that there were no `identification guides' for the species found in California. Therefore I began searching the Internet, libraries and museums for checkdamsels, photographs and information. I want to especially thank Ron Lyons who made available the Checklist of CA Species and who was a great beginning `tutor' in all things Odonata, and Dennis Paulson of Washington, who along with Rosser Garrison did the research to create the information used in Ron's list and who has been invaluable to me in learning about these fascinating insects. Also of great encouragement and help have been these other experts, any of which I'm certain would also be willing to help you if you have questions: Andy Rehn, the staff at the California Academy of Science's Department of Entomology, Roy Beckemeyer of Kansas, Bob Barber of New Jersey and Mark O'Brien of Michigan. I'd of course also like to thank all of the photographers. Both those who have allowed me to link to their sites in the web sites photo column, and those who have sent me their photographs &/or jpegs to use on the website. Their photos have made learning to identify dragonflies and damselflies possible.



The damselfly families with links indicated below have been found in California.

For children, grandchildren & your inner child!



For help in identifying CA Odonata, go to "FIELD KEY TO ADULT CALIFORNIA DRAGONFLIES (ODONATA)" .
This is a BETA version key and it includes damselflies. It needs field testing. (There is also an OLD key using wing venation and sexual appendages in "Aquatic Insects of California" by Unsinger, but this has been out of print for several years. The California Library system should have copies of Unsinger's book available for in-library reference work).

To learn more about these fascinating insects go to Ron Lyon's informative site:
Damsels and Dragons - the Insect Order Odonata.

To encourage dragonflies and damselflies, build a pond "and they will come!"
