One 5th instar and one 3rd instar on Asclepias sullivantii. The 3rd instar was caught in a spider web I had walked into. The spider was attacking the caterpillar, and the caterpillar was discharging green liquid onto the leaf and spider. I started removing the web which disturbed the spider and it moved away from the caterpillar. I killed the spider and removed the web from the caterpillar.
