I have been finding these 2″ long fuzzy things all over my backyard. I’m not sure where they are coming from, but I’m hoping it’s not some sort of insect or nest that may damage trees, fruits and veggies in my yard. I have a picture here if one in a bush in my yard but I don’t think it grew there – may have just landed there. Insect? Piece of a plant? I see about 20/day in my backyard. I’m in the Beaches so it’s just starting to warm up here.
When the forsythia bloom is also when Eastern Tent Caterpillars hatch from eggs masses on host trees so it is possible that is what you are finding. Here is a link with some very good detailed pictures for you to consider:
