Fonscolumbii Group

 

 

The two species of this group are both migrants, and as such are unusual members of the genus. The eggs of these two species are not known to overwinter, another unusual trait for this genus. In fact, these differences along with morphological and genetic differences have led to the proposal to remove these species from genus Sympetrum.

 

I wonder if Sympetrum dilatatum doesn't belong in this group as well? This species, endemic to the islands of Saint Helena, has not been seen or recorded since October, 1963.
