It’s milkweed bug time in the garden. Cathy and I are both big fans of pretty much any species of Asclepias. This one is Asclepias curassavica, often known as scarlet milkweed. It’s growing in a container on our back patio and it really attracts the insects. I had a photo of a Monarch (Danaus plexippus) on it recently and today’s photo is of the aptly named large milkweed bug (Oncopeltus fasciatus). We also have a good colony of oleander aphids (Aphis nerii) and I may publish a photo of those, unless we get around to taking care of them before I do that. Like many insects that feed on milkweed, these bugs accumulate toxins from the plants which can “potentially sicken any predators foolish enough to ignore the bright colors which warn of their toxicity.” (bugguide.net)
