Black and orange striped Blister beetles were pictured twice under black webspinner but are not a webspinner. They are about .4 inch to .8 inch long while webspinners are about half that long. This species is the worst plant defoliator of blister beetles. They occur in large sparms and provide a low toxin called cantharidin. Cantharidin causes blistering on hands if sensitive enough or blistering of intestines of livestock that eats the plants tainted from the beetles feeding on the plant.
