Hi, there are some species that even lay larvae that almost immediately become pupa-s, one at a time, these are the so-called Pupiparans: Hippoboscidae, Streblidae, Nycteribiidae. The photo is very interesting!

Sarcophagidae (like in the link) are commonly larviparous. Many tachinidae have similar strategies.
