Citrine Forktail

At the first pond at Hacienda La Pacifica, Costa Rica on 7 July 2017, we encountered this immature, female Citrine Forktail. This damselfly enjoys a curious distribution. It ranges from southern New England across to Iowa, south to southern California and the southwestern United States. From there it is found through Mexico south to Venezuela. Isolated populations are also occur in the Galapagos Islands and the Azores.

Mating Citrine Forktails are infrequently seen. Females apparently only need to mate with one male to fertilize all the eggs they will lay. In the Azores, males are unknown. The females there lay unfertilized eggs that develop into more parthogenetic females. In this respect, Citrine Fortails are unique among the Odonata. This photo was taken by Erika.
