Unknown caterpillar observed
Observation: Something is nesting in alder leaves, causing them to curl and eating foliage. I have not seen a caterpillar with this before, with a web-like nest inside a leaf curl. It takes a long time for trees to reach any height or maturity in our coastal environment. Don't want a die-off. Becky Savo
