Old photos from 2025. Green looper caterpillar (pictures 1-3), ate grass. Settled on white fabric roof in loose white cocoon. No pupa formed, but the caterpillar became a green mass that appeared to contain some parasite (picture 4). About ten days later, the mass had turned brown and looked like a cluster of cocoons/pupae (picture 5). I watched this for almost a year, but could never see anything hatch from the cluster. Assume they were very tiny wasps that escaped through the fabric at some point.
