Oncopeltus faciatus on our Asclepias curassavica
We have a patch of Asclepias curassavica ("Mexican" milkweed) that has delighted Monarch butterflies this summer. Now the plants are infested with bugs that turn out to be Large Milkweed Bugs, Oncopeltus fasciatus. They are in several sizes and happily eating away. My wife was startled to see them but I said we should let them be. I haven't found anything online that suggests they a pose a risk to humans. Is there a risk? (I suppose their accumulated toxins could make a human or a dog very sick but I have no plans to eat them, and I will keep my dog away from them.)
You do not need to worry about these bugs.
