From the pupa emerged this Diptera
Cecidomyiidae?

Male in supertribe Cecidomyiidi. Based on host plant, probably Cecidomyiini. European literature may provide more specific ID. A quick search tells me Thecodiplosis brachyntera is a possibility because related species mine needles. Cecidomyia is found in resin, so is less likely.

I checked some literature. According to Gagné (1978), "Larvae of Cecidomyia pini leave the pitch mass to spin coccoons in which they pupate."
