Metamasius callizona (Chevrolat) is native to southern Mexico and Guatemala. It was detected in Broward County, Florida, in 1989 and has spread to 20 counties in southern Florida, where it devastates populations of native epiphytic bromeliads and also attacks cultivated bromeliads. Larvae mine into stems of larger bromeliads, killing them. New data were obtained at ≈25°C and a photoperiod of 14:10 L:D to optimize cultures of this insect to serve as hosts for the production of biological control agents. After pairing with males, it took an average of 28.9 d (±17.8, range 8-89 d) for females to begin laying eggs; thereafter, each female laid eggs for the remainder of her life, or within just a few days of her death. The total duration of life of 75 ovipositing females averaged 156.4 d (±96.7, range 26-387 d); their lifetime egg production averaged 39.6 eggs (±40.0, range 2-188 eggs).
