Coccus viridis is a soft scale insect (Hemiptera: Coccidae) and major agricultural pest with a wide tropical and subtropical distribution. It reproduces parthenogenetically via thelytoky, with females producing 50-600 eggs that hatch within minutes to hours beneath the mother's body. The species completes its life cycle in 47-51 days at 25°C, with three nymphal instars before adulthood; first-instar nymphs actively disperse as 'crawlers' while older instars and adults become sessile. It is polyphagous, feeding on phloem sap of over 200 plant genera in 72 families, with primary economic damage to coffee, guava, and cacao crops.
