Pro Natura ha designato la cavalletta celeste (Oedipoda caerulescens) animale dell'anno 2023. Diffusa soprattutto in Ticino, la maestra di mimetismo al suolo è praticamente invisibile, mentre quando balza in aria mette in atto uno spettacolare gioco di colori.
Amante del caldo, potrebbe anche apprezzare i mutamenti climatici, ma la crisi della biodiversità costituisce una minaccia anche per lei, indica l'associazione ambientalista in un comunicato. In Svizzera ambienti del genere si trovano soprattutto in Ticino e in Vallese.
"L'animale dell'anno necessita di ambienti con caratteristiche ben precise", spiega Florin Rutschmann, specialista di ortotteri e incaricato per le riserve naturali presso Pro Natura Argovia. La cavalletta celeste predilige spazi aperti e soleggiati con una leggera copertura vegetale, per questo si insedia nei prati secchi, nelle distese di ghiaia delle aree golenali oppure in siti ferroviari o industriali in cui pian piano avanza il verde.
