Gall and life history
Massalongia papyriferae forms bud galls on the paper birch, B. papyrifera. The mature larva drops to the leaf litter to overwinter in a bottle-shaped cocoon. Adults emerge in spring (Gagné 1967).

This species is of some economic importance because the larvae bore within and kill the affected buds of paper birch, Betula papyrifera. In the fall the larva makes an exit hole and drops to the duff where it forms a cocoon in which it apparently overwinters before pupating in spring.

Galls appear in midsummer. Full-grown larvae drop to the ground in late September and form cocoons in which they overwinter... Several larvae occur in separate cells in the cortical enlargement. Bud and stem mortality results from girdling. Host: B. papyrifera...
