What species caterpillar/larva is this? #855090

Asked November 10, 2023, 4:35 PM EST

Hi, I was planting bulbs in my garden today (11-10-23) and came across this caterpillar. I was using an auger, so I'm not sure if it was in the soil or on top of it. What species is this and is it harmful or invasive? Thanks!

Thanks for the question.

We believe that this is a caterpillar for the Large Yellow Underwing moth (Noctua prouba). It belongs to a family of moths known as Owlet moths. They generally are most active at night. They are important pollinators. See:
