Description of specimen

Lots of these pods/tent like cocoons in the brush near the parking lot. I thought they were spider nests at first but when I zoomed in with my camera I saw the caterpillars on the webs so I snapped some pictures to look up what they are. I found 2 possibilities one being a gypsy moth caterpillars.


Dear Debbi, thank you for your report. Luckily, they are not Gypsy moth. Gypsy moth don't form any "tents". We have our own tent caterpillar here in Oregon, the western tent caterpillar. Here is more information:
Thank you and best regards, Helmuth Rogg
