Dortus primarius Distant (Miridae: Deraeocorinae) was observed to feed on thrips and other soft bodied insects in the field. Biology, morphology and feeding potential of this species were studied for the first time in the laboratory (at 26 ± 2ËšC and 65 ± 2% RH) on UV irradiated Corcyra cephalonica (Stainton) eggs. A total of five instars were observed, with nymphal duration of 17.2 days. Mean fecundity was 127.6 eggs per female. Female longevity was higher than male. One nymph could consume a total of 363 C. cephalonica eggs in its life span. Adult male and female fed on a total of 713 and 1014.75 eggs, respectively. Cost of producing 100 D. primarius nymphs and adult nymphs neonate/first instar was INR 10.34/- and INR 200/-, respectively. In this paper all immature stages, eggs and adults are described with live images. Results showed that this species could be reared on UV irradiated C. cephalonica eggs and bean pieces successfully. Further studies are needed to evaluate this species against insect pests in field.
