Studies on the biology of the chrysan­themum leaf miner Liriomyza trifolii (Burgess) showed that oviposition occurs under the epidermis of the upper surface of the leaves and that hatching takes place 6-10 days later. The larval stage has three instars that can be differentiated by the size of the mouth hooks; the larvae complete their development in 14-31 days; the prepupa lasts 5-8 hours and the pupa, 15-18 days. Female longevity has an average of 11 days and the males, 5 days. Females mate with different males since the day of emergence. A single female can lay an average of 78 viable eggs. Oviposition starts two days after adult emergence showing a peak of viable eggs laid on the fifth day. Between days 5 to 10, the females deposit 74%  of the total viable eggs.
