Cicadas eat sap.
 Though these cicadas' life cycles  can vary from 19 or more years as underground nymphs, their emergence above ground as adults is not synchronized, so some members of each species appear every year
 Most cicadas are diurnal and rely on camouflage when at rest, but some species use aposematism-related Batesian mimicry, wearing the bright colors that warn of toxicity in other animals; the Malaysian Huechys sanguinea has conspicuous red and black warning coloration, is diurnal, and boldly flies about in full view of possible predators
