I guess what I meant that most caterpillars of ironweed were borers, according to a few websites that I found thru Google. Heres one passage: The caterpillars of several moths feed on Ironweed, including Grammia parthenice (Parthenice Tiger Moth) and Perigea xanthioides (Red Groundling). Caterpillars that bore into the roots or stems of Ironweed include Papaipema cerussata (Ironweed Borer Moth), Carmenta bassiformis (Eupatorium Borer Moth), and some Polygrammodes spp. (Pyralid Moths). The bitter foliage of Ironweed deters consumption by mamamalian herbivores  it is known as an 'increaser' because it is one of the last plants to be eaten in overgrazed pastures.

Hard to tell without a picture, especially when you can't make a connection to a food plant at the same time. Here's a website that helps you identify caterpillars by features (colors,stripes, fuzzy, etc.) Hope it helps. Here is a link that might be useful: Discover Life Caterpillar ID page

Eeeewww, Gillian......I looked at the website you mentioned. I sure wish they didn't show such swarms of them ! I searched the pictures for my caterpillar, and didn't find it yet. I took a better look at the darn thing, cut the stem of the lily ( one I don't like anyway) and double bagged it and threw it in the garbage. I don't think I have the stomach to look again on that website or any others for a while. I guess I can do without knowing what it was. Thank goodness cashews are high in calories and not something a person really "needs" to eat to survive, as I doubt I'll be eating any of them anytime soon now, LOL! My stomach hurts. My "ick factor" tolerance is pretty low. Konrad - If you do a thread on caterpillars, please put a subject matter warning in your first post =:) I don't think I'll appreciate your pictures of them like I do all your other pictures =:)

You should do a google image search and figure out what these are. I can never remember the difference between centipedes and millipedes, so I googled it: 'Centipedes are beneficial in the garden because they prey upon other insects. Millipedes are fine in the garden, since they mostly eat rotting detritus.' If you have millepedes in a second floor, you might have a serious problem with moisture behind the walls or under the roof somewhere. If I found these in my house, I'd want to do some scouting to find out what they might be eating. Good luck - I know how creepy it is to find insects in your house! We recently had a problem with a light timer that was supposed to control the light at the front door. When the electrician took it out of the wall, the whole switch area was full of tiny ants. I still can't touch that switch without thinking about what might be behind the wall.
