Golden Tortoise Beetle

An iridescent ball appeared on the kitchen wall:

Despite the silvery shine under LED lighting, it was a Golden Tortoise Beetle:

The iridescence shows up better with a bit of underexposure:

Golden Tortoise Beetle - left top - dark

Transparent armor: who’d’a thunk it?

Mary spotted one in the garden some years ago; I’ve never seen such a thing.

    1. Not something I want to find on the kitchen wall!

      Mary does battle with slugs in the garden, to the extent of applying Sluggo (iron phosphate) around seedlings; after the plants take off, they’re on their own.

  1. I’d seen some distinctive golden beetles on morning glory vines. They turned out to be Aspidomorpha tecta (fool’s gold beetle). Their coloring is also not a pigment but an optical effect relying on interference and dichroics, in this case, a structure known as a “chirped stack”.

    1. Mary found a similar critter with a vivid gold iridescence on a squash plant, so maybe that’s what we have, too.

      Given that I’ve never seen any before, they must be having an irruption.
