Explanation of Names
Pristerognatha agilana (Clemens, 1860) was synonymized with Pristerognatha fuligana by Oku (1970) and reinstated by Miller (1985) based on genitalia but authors and websites continue to refer to this species as Pristerognatha fuligana as of 2017. DNA barcoding supports Miller (1985).
Wingspan 11-14 mm. (2)
DNA confirmed but as of 4/2017 BOLD still uses the name Pristerognatha fuligana which is extralimital. The species page includes two BIN groups with one being strictly new world and the other old world. The new world group refers to Pristerognatha agilana (Clemens, 1860).


Believed to fly from April to August and eggs are laid during this period in the stems of touch-me-not balsam and Himalayan balsam, where the stem-mining caterpillar feeds and hibernates. (3)
Larvae are stem borers of touch-me-not, including jewelweed (Impatiens capensis), as well as tansy (Tanacetum) and Himalayan balsam. (3), (4), (1)
