Unknown Psychidae (Perhaps?) - Thyridopteryx ephemeraeformis

Unknown Psychidae (Perhaps?) - Thyridopteryx ephemeraeformis
Chicago, Cook County, Illinois, USA
Size: 1 inch long including bag
There were about 100 or more burrowing into a tree which was different from all the rest of the trees on the block. I couldn't make out what kind of tree it was. They resemble Bugle chips. I'm really dying to know what they are as I have grown up in Chicago and never seen anything like this. Here's where you can view more images of the organism and tree: http://www.inaturalist.org/observations/3605393
