General comments:
Mompha divisella and Mompha bradleyi are of similar appearance and naming of adults usually calls for genitalia examination. Larvae of divisella mine the stems of Epilobium montanum, palustris, lanceolatum, parviflorum and adenocaulon and there are few other obvious signs than a pea-sized swelling of the stem at a node. M. bradleyi is so far known only on Epilobium hirsutum.  | Determination by Genitalia Examination Required | |
