Chrysocus cobaltinus

Chrysocus_cobaltinus

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!

Phrynosoma blainvillii

Alli and I explored a back route into Topanga State Park this morning, then hiked the familiar and much-loved Musch Trail. (Who was Musch? I’ll have to ask Suzanne, she’ll probably know.) We spotted a Blainville horned lizard close to where I saw one (my first!) last year. Nice!

How to read nature

While camping, I read and enjoyed this short book by Tristan Gooley. My main takeaway is this (far from simple) exercise: Wherever/whenever you are outdoors, ask yourself “In what direction am I looking?” and “What time is it?“ (Learn to) use nature to find the answers. I’d like to get better at this.
