Cicada The Cicadoidea, cicadas (/sɪˈkɑːdə/ or /sɪˈkeɪdə/), are a superfamily of insects in the order Hemiptera, suborder Auchenorrhyncha (formerly part of the obsolete Homoptera), along with smaller jumping bugs such as leafhoppers and froghoppers.he periodic cicadas spend most of their lives as underground nymphs, only emerging after 13 or 17 years, most likely to reduce losses by satiating their predators. Cicadas have been featured in literature since the time of Homer's Iliad, and as motifs in art from the Chinese Shang dynasty.

Hydroxylapatite Hydroxylapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. Hydroxylapatite is the hydroxyl endmember of the complex apatite group. The OH − ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxylapatite powder is white.
