Hi-yo Silver - Plutella

Hi-yo Silver - Plutella
Incredible Edible Park, Irvine, Orange County, California, USA

Size: approx. 12mm

Is that length or wingspan? If length, it may be too big in which case consider Rhigognostis poulella. I would assume it's not that species because of range.

That's length, Steve.
Thanks for your comment.

Quite a coincidence
(See comment below. I wanted to delete this comment, but couldn't.)

Possibly a Diamondback Moth, Plutella sp.
Hi Ron, it's interesting that we both got the same moth on almost the same date on opposite sides of the continent. At the moment I can't be sure that this is not Plutella xylostella, commonly called the Diamondback Moth. The silvery coloring on your and my specimen is different from the typical Diamondback (white to off-white). Also, neither of our moths show the "diamondback" pattern responsible for the common name. But a fair percentage of the real Diamondback vary from the typical and show little or no white indentations in the the brownish wings.

Here are two photos of the moth I got on the 24th of April at Bowie, MD, close to Washington, DC:

There are two typical Diamondbacks in the Guide here:

Finally, you might be interested to know that the Diamondback, introduced to North America more than 150 years ago, is a striking case of an insect that has evolved resistance to more than 80 pesticides. The list at this link cites a number of California locations where such resistance has been noted.

That is quite a coincidence.
Another: You probably live close to my D.C. daughter, who is just over the MD border in Friendship Heights.

I'm sure we have the same type insect. The CA locales listed in the link are well north of here in areas that are currently more agricultural than mine. I was surprised to see resistance to malathion. Interesting stuff!
