Large Milkweed Bug (Oncopeltus fasciatus)

We found this beetle on a couple of Green Comet Milkweed (Asclepias viridiflora) plants growing in the Oconee WMA on the east shore of Lake Oconee just north of the dam. This was one of the easiest bugs to identify. Just ‘google’ ‘milkweed’ ‘large’ ‘orange’ ‘black’ ‘bug.’ And up it comes: Large Milkweed Bug (Oncopeltus fasciatus).

In spite of photographing more than a hundred different asclepias plants, we’ve only seen these bugs on a couple of Green Comet Milkweed plants at this location.
