Acting on the information given me by a woodchopper who had seen hundreds of green flies under the bark of a tree he had felled a few days previously, I made a further investigation, and upon reaching the locality found several dead Lace wing flies crushed under the bark of a Tamarack tree he had been sawing up. Furthur search undert the bark of a tall dead Tamarack (Larix occidentalis) which had just been felled, resulted in a rather unique cathch on removing the bark, which peeled off easily from the butt end, hundreds of lively specimens of the minute Tineid, Lyonetia speculella, Clem., were found.
