  • This study was performed to investigate the biological characteristics of the brown lacewing Micromus angulatus (Stephens) at four different temperatures (15, 20, 25, and $30^{\circ}C$) and $70{\pm}10%$ relative humidity under a photoperiodic regime of 16:8(L:D) h. The developmental threshold and effective accumulative temperature from egg to pupa for M. angulatus were $9.6^{\circ}C$ and 270.3 day-degrees, respectively. The developmental period of egg, larva, and pupa at $25^{\circ}C$ was 4.4, 5.5, and 6.9 days. respectively. The longevity of an adult female M. angulatus was 34.9 days. The oviposition period for M. angulatus was 28.7 days, in which it laid a total number of 515.2 eggs during its life span. The maximum number of eggs laid by a female in a day was 54.8. Daily consumption by M. angulatus at $25^{\circ}C$ was 18.9 $1^{st}$ instars, 47.2 $2^{nd}$ instars, 57.7 $3^{rd}$ instars, and 91.0 adults of the glasshouse potato aphid, Aulacorthum solani. Therefore, M. angulatus could be a promising biological control agent against aphids.
