The complete life cycle of O. ferruginea is described for the first time, represent the first complete life cycle described for an odonate in Mexico. The 17 larval instars obtained are described and illustrated in detail, from prolarva through F-0. Two egg batches of different females were obtained in the field and were subsequently reared in the laboratory.

The distribution and relative abundance of the sibling species Orthemis ferruginea (Fabricius, 1775) and O. discolor(Burmeister, 1839) in North and Middle America (Anisoptera: Libellulidae)
The sibling species Orthemis discolor and O. ferruginea are distinguished by coloration, although one structural characteristic can be used to differentiate many females. Further information on the distribution and relative abundance of the two species in North and Middle America is presented.
