Research on cicadas is fairly recent and still leaves a lot of room for the work of entomologists like Gérard Filippi. Their family, the Cicadidae, was described by the French entomologist Pierre André Latreille in 1802. In the 1950s, only eight species were known in the country. Today, twenty - including sixteen in Provence - and around 4,500 worldwide have been listed. While the most common, such as the gray cicada (Cicada orni), widely present in the Sainte-Victoire massif, and the great common cicada (Lyriste plebejus) are well documented, this is not always the case for rarer species or less easily observable ones due to their size like the pygmy cicada (Tettigetta pygmea).
