Cicadas are herbivore insects, known for their size and the incredibly loud and distinct sounds they produce. They live most of their lives underground. This underground stage can last up to 17 years, depending on the species. Be loud and stand out with this pendant. The attaching hole is 1mm in diameter, fitting most chains. This cicada has a wingspan of 6.6cm with a height of almost 4cm, and a thickness of 1mm. Fragile but daring.
