The lateral branches had a horizontal "flattened appearance".
Only roughly 2mm long. Diurnal. In a peat swamp with lots of cherries, blueberries, spruce, larch. There were many of them in the shrubs along the trail, I'd say about 10 per square meter. Thedy seemed to land on the cherries the most but only rested for about 5 seconds before moving on. Is it a species of Lomographa, maybe?
