My past life
Cicada sp. exuviae. Although it's possible to advance an ID it's better not to risk it.
I don't have knowledge of a key for Cicadidae Exuviae, it can be the Cicada orni, or the Cicada barbara lusitanica, the two species that I know that are described for the portuguese territory.
Adult size can be just a best guess, Cicada orni is a little big that the congener, and this exuviae that were found are quite small while the best way to distinguish them in adulthood is to listening to their particular chants.
Given all the facts, just remains the record of 23 exuviae found, all probably from the same species, or not.
Sometimes is hard to track all the past life of the cycle of a Cicada.
