Bird's-foot Trefoil mines

At Church Village yesterday I noticed a few Trifurcula leaf mines during Marsh Fritillary larval web surveys. They are similar to those I found at Lanlay Meadows last year, which I concluded were the work of T. cryptella rather than the rarer T. eurema (which isn't know from Wales). Yesterday's mines were on Greater rather than Common Bird's-foot Trefoil, which suggests cryptella.
