Stem borer, Parthenocissus

Stem borer, Parthenocissus
Footbridge Farm, Allamakee County, Iowa, USA
February 17, 2018
Size: 3/8"
Overwintering stem borer in Parthenocissus

I caught this larva in the middle of a U-turn inside the Parthenocissus vine. Here you can how it has begun boring "backwards" through the stem such that its head (left arrow) now faces the same direction as its rear end (right arrow)

Another example from February 2018


and one from August 2018


Puparium and reared adult, 2022
