The cicada is a curious insect that serenades hot summers with a rhythmic reverberating chirp. Many cicada species appear annually, while some can live underground for up to 10 years. They then emerge at once to slowly make their way to the treetops to molt, sing and reproduce. Cicadas become an abundant food source and boost of energy for birds, small mammals, and other creatures. This design is just over 3.5 inches.
