Observation date: August 31, 2017
Submitted by: Exo514
Specimen type: Photograph
Observation notes: Quite possibly the largest Monarch caterpillar I've seen in the wild in years. It was just beginning to chew its way through the middle vein of a Milkweed leaf, but once I got near the specimen it began twitching erratically. It eventually started eating again before twitching once more.
