I happened to pass a hardware shop yesterday and was going to go in but they were closed. I went to the next shop which I thought was another hardware shop but was a paint shop. I asked the gentleman if he had any screening. He said no, but the guy next door probably did, but he was already closed. He asked what I needed it for and I told him caterpillars. Instead of giving me a strange look, he took me over to the paint strainers. He said he wanted to be honest, screening was a lot cheaper, but if I needed something in an emergency, he had one gallon paint strainers for 1.69 and five gallon ones for 1.99. I appreciated his honestly and bought a five gallon one. I see lots of possibilities. Since it is flexible and can easily be cup up, I can cut a secion and put it over almost any container I might be using to rear caterpillars. I could put it on the side and floor of my aquarium in case anyone falls while emerging from their chrysalises. I dont know if this item has been mentioned before but just wanted to let people know that I think it could have a lot of good uses.
