Spotted last Sunday on Amsinckia in the East Field, the plant bug Plagiognathus moerens:
Plagiognathus moerens on Amsinckia.
Plagiognathus moerens is a specialist feeder of Amsinckia and other Boraginaceae. It’s very little studied — the only references in the scientific literature are to the taxonomic description. So far as we can tell, our photos from the BFS are the only ones available on the internet. Many thanks to WonGun Kim at BugGuide.net for the identification!
