 Collected from bird nest-box occupied by Great Tit. Could it be Mycetophilidae?

 Mycetophilidae do not form a puparium, pupating outside of the last larval exuvia. As a result, legs, wings, and head sheaths are distinct. The pupae you have photographed here belong to a family of Calyptratae or Acalyptratae.

 I found probably the same one, this time in tree hole. Is there something new that makes this pupae possible to determine to the family level?

 Seeing these, I am reminded of Heleomyzidae. What size are they?

 All pupae fall between 4,5-5,5 mm.

 Hopefully you will be able to rear some adults, or find a puparium with an adult ready to emerge. Usually the male genitalia are well formed at that stage, and can be used to identify the species.
