Maggots of this fly emerged from the pupa of a ladybird (Megalocaria dilatata pupa) on 2.v.2021. They turned into pupa on the next day. Tony Irwin opined that the fly may belong to the Genus Phalacrotophora.

The fly emerged 2 weeks later (on 17.v.2021). 6 species of Phalacrotophora are known from our part of the world, viz. P. decimaculata, P. fasciata, P. flaviclava, P. jacobsoni, P. punctifrons and P. quadrimaculata.

I have no idea how they look like. Grateful if someone can identify this species here.

Yes, this is Phalacrotophora and mostly resembling P. beuki that is know from Western Europe. The posteroventral part of segment 8 much more produced than in beuki and the overall coloration is more pale yellowish to orange.
