Submitter does not have a specimen
Many nests, looking like a large sack made of spider webs. Inside each sack were thousands of small round brown eggs. Within the sack were a worm or caterpillars that had stripes and "green" blood. No moths had developed yet, that I could tell. We cut out all the sacks and infected leaves which the caterpillars had eaten. All this was taken to the dump. We sprayed the tree with a natural 2 in 1 spray, washed down the driveway and sprayed the driveway as well. Days later, I found 3 more caterpillars and I stepped on them. They squirt out green "blood".
Feel free to call me 541-469-2443 or come by.
I remember perhaps 10 years ago on Hwy 199, (Ca.) a road we at the coast must take to go to Medford, All the trees along that area were covered in a spider web looking nests also.
