Roughly equal proportion of males and females (total number about 20) was found in a container with (mostly) lepidopteran pupae including a couple of Psychidae cases and some cocoons of Hypera collected on Galeopsis speciosa (weevils mostly already emerged). Size: male ca. 1.5 mm, female ca. 2 mm. Hosts of Necremnus include both Psychidae and Hypera, yet to me it looks more like Pnigalio. Subject changed from Eulophinae, Necremnus/Pnigalio? to Elasmus, ID by proctoss.
