The life cycle of Optatus palmaris Pascoe was determined in laboratory. Observations were done from August 2011 to July 2012. Alimentary habits and fluctuations of eggs, larvae, and adults were observed under field conditions. Studies were done in Compostela, Nayarit, Mexico. Optatus palmaris completed its life cycle in 216 days; egg 5 days, larva 73 days, pupa 25 days, and adult in 112 days. Adults were observed during the day and night doing damage to fruit ready to be harvested. Density per fruit ranged between 0.1 to 0.2 adult producing a percentage of 68 to 79 damaged fruits and an affected area of 38 to 98%.
