Gall on Fumaria c.f muralis. Inside I only found what seems to be a puparium. Thought it was empty until I observed this failed pupa shortly after.
Hidden cell in a lettuce sp. Cut apart 15 stems to find these two galls. Host was a giant example with galls as well
If ID is correct, any spécial request, @friesen5000 and @megachile and @louisnastasi
Several of these wasps emerged from this leaf loaded with galls.

On Silphium, shown in 3rd photo. Upper and lower surfaces shown. Gall large enough to be visible on a leaf in the lower area of the 3rd photo. Stone Road Glade Natural Area
