Lorryia formosa Cooreman has been collected on many different host plants around the world. The biological cycle of this species was studied at 28 °C with mites collected from a rubber tree crop. The life table was constructed based on sixty individuals. The average lifetime was 37.43 ± 20.23 (SE) days, and the rm was 0.08. The sex ratio was totally female biased, and unfertilized eggs developed into females. This is the first record of thelytoky in Tydeoidea proved by rearing.
