Craggy Rocks, Winneshiek County, Iowa, USA
October 7, 2021
Size: 4+ mm
October 4, 2021: collected leaf mines on Ironwood, Ostrya virginiana, all evacuated
October 7, 2021: but one of the leaves had this case still attached (not alive). There was no sign of feeding other than the small spot where the larval case was attached.
The case does not look like the Coleophora ostryae cases posted on BG.
