They make a bag and it hangs off small limbs. The bag is silk lined and very tough....hard to pull one apart using both hands, thumb and index fingers. It is decorated with leaves and on cedars (cedar leaves are short and slender), little bluish balls appear also that show up on the female gender tree for that year....different years, different trees are girls.
They come up out of the bag to eat the leaves off the host tree. If you catch them out eating you will see the head protruding out of the bag and the incisors just making a mess of the tree.
Since trees take in CO2 and release O2 and in doing so grow, if you remove enough of the leaves the tree can't make the transition adequately and it will die. 200-300 bag worms on a 20' cedar in time will and do kill them. No brag, just fact and that's the population density I get when the butterflies hybernate. So, for me, take that number x the 160 trees I have and you are talking about a lot of worms.
On other trees, I have no idea as I never see them on anything but cedars and they are on there by the 100's. They are obviously butterfly larvae as you don't have any until the butterflies migrate in the spring. The ones that get me are the smaller ones, like the one that's tomato worm green with the big dot on each wing, or the yellow ones of the same size. When 2 or 3 groups of them migrate, I have 2 or 3 sessions with the worms.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
