And So It Goes….

July 14th, 2012. Some of the Maroon Carolina Milkvine (Matelea carolinensis) seed pods are ripening. And right on schedule, Large Milkweed bugs (Oncopeltus fasciatus) have turned up out of nowhere to mate and lay eggs on the pods. The resulting young will feed on the seeds of milkweeds and milkvines.

Before long, the nymphs will emerge and will feed on the seeds

The nymphs will eat the meat and leave a halo. One of the reasons the world isn’t over-run with milkweeds and milkvines.

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.
