I believe this is a beetle, and one I have never seen before. Its colour was eye-catching against the green of the leaf.
There’s a spot at a nearby lake where the frogs like to congregate. When we walk by it we listen for a splash and usually see a couple of frogs. Although I’ve featured this photo before it made me smile when I came across it recently. I hope this slightly re-edited version has the same effect on you.
We were taking photos of an adult and osprey chick on their nest at a respectful distance (with long lenses and at least 40 feet below 😏 ) but the osprey parent was not happy at all. It flew from the nest, circled above and flew uncomfortably low and close. We took the hint and walked quickly back to the car, content with the photos we had got.
The insect under question was misidentified as a Milkweed Beetle when first posted. (See Steve Gingold’s comment)
I was happy to get this shot so late in September as we’ve had several frost advisories at night. The milkweed bug didn’t seem to mind though. I had also planned to take landscape shots that morning, so this wasn’t taken with my macro gear. The natural light provided this interesting effect.
