Unidentified larva associated with a leaf gall#2 on Lead Plant

Unidentified larva associated with a leaf gall#2 on Lead Plant
Sheeder Prairie, Guthrie County, Iowa, USA
July 16, 2019
I've seen herbivory on these galls

but not frass and a non-gall midge or wasp larva

July 9, 2019: collected leaf galls on Lead plant, Amorpha canescens, for yet another attempt, unsuccessful, to get adult flies
July 16, 2019: looked close, on 3 galls there was frass, leaf herbivory, and perhaps outside of the gall herbivory. On one gall found a tiny larva (but did not look close at the other 2 galls)
January 4, 2019: finally cleaning the unsuccessful rearing vials (and double checking), cut open a leaf gall #3 which was full of frass, including a circular weaving of frass

Surely a lepidopteran intruder...
but I have no idea beyond that (other than that it seems like such things usually turn out to be gelechioid).
