Grote’s Underwing Moths (Catocala grotiana) belong to the moth household Erebidae. Native to Arizona, Utah, Colorado and different components out west. Though they’re not often encountered within the Northwest. There are over 250 recognized species of Underwing moths on this genus and roughly half stay in North America, with the lions share being in the US.

Members of this genus use cryptic coloring to mix into their atmosphere in an ideal bark-like camouflage that makes them just about inconceivable to see.

The one pictured right here was discovered nectaring on the Nodding Groundsel Flowers and photographed round 4:00 within the afternoon. After I posted this image to Fb a good friend of mine, Eric Eaton over at Bug Eric commented “What’s unsuitable with this image?” I used to be perplexed for a bit as to why he requested that. Then he identified this can be a nocturnal moth, out in the course of the day, nectaring at flowers. Uncommon conduct for a nocturnal moth to make sure, however I’d guess this can be a evening flying moths model of a “midnight snack.”
