This iridescent little beetle (about 8mm long) was on a milkweed plant at the Park yesterday. So bright and metallic!
Both adult and larvae C. cobaltinus life stages eat dogbane and milkweed species. These plants contain toxic molecules known as cardenolides, which the beetle is resistant to. In fact, it stores the cardenolides in its glands, and uses them against predators.
Cobalt Mikweed Beetles are similar to click beetles in being able to launch themselves a couple of times the length of their body. Little but mighty!

It’s been a while since I drew an insect with Trisha from Insectopia. I learned a new term: SULCUS (singular) / SULCI (plural) for folds in an insect’s exoskeleton. It also refers to the depressions or grooves in the brain.

The water in the pool is getting really low; in a few more weeks it will have evaporated completely. I was observing some rather large organisms running about under the murky water, and wondering what they were. I was distracted by some mating flame skimmers overhead, and watched as they completed their copulation and the female proceeded to repeatedly dip the end of her abdomen in the water.
Now that I’ve done a little research on flame skimmers, I’m pretty sure that the critters I see underwater are the dragonfly’s nymphs. Hopefully they’ll have time to metamorphose before their habitat disappears for the season.

As I was falling asleep last night, I could hear adult and young Great Horned Owls out in the darkness. The babies were screaming for food; I imagine the parents were hooting “Patience little ones! We’re coming!“
