The litchi stink bug, Tessaratoma javanica (Thunberg, 1783) (Hemiptera: Tessaratomidae), is an important pest of litchi in eastern India, while information on its egg parasitoids in Bihar remains limited. This study documented clutch-level emergence and progeny composition of Anastatus bangalorensis Mani & Kurian, 1953 (Hymenoptera: Eupelmidae) from naturally collected T. javanica eggs on GI-registered ‘Shahi’ litchi in Muzaffarpur, Bihar. During May 2026, 35 naturally laid egg clutches were collected and maintained individually under laboratory conditions until emergence ceased. Host bugs and parasitoids were identified morphologically, and parasitoid number, sex and emergence sequence were recorded for each positive clutch. Of the 35 clutches, 16 produced T. javanica, nine yielded A. bangalorensis, one yielded an unidentified Ooencyrtus sp. (Hymenoptera: Encyrtidae), and nine showed no emergence. The nine A. bangalorensis-positive clutches contained 169 host eggs and yielded 169 adult parasitoids. The progeny comprised 166 females and three males, corresponding to 98.22% females and a female-to-male ratio of 55.3:1. Females emerged before males in all three clutches that produced males. The observations provide baseline evidence of A. bangalorensis occurrence in Bihar and quantitative information on clutch-level emergence and progeny composition. Because parasitoid emergence was recorded from only nine clutches, these results should be interpreted descriptively and not as evidence of population-level parasitism or biological-control efficacy.
