Pink-spotted Hawkmoth (Agrius cingulata) Life History

Caterpillar when found in Salineño, TX. 10-1-11


10-5-11; note new instar has knobby skin


A new instar brings a new color, 10-9-11

Mature caterpillar, 10-14-11

Fresh adult Agrius cingulata, 11-3-11

I found this caterpillar while beating Red Center Morning Glories, Ipomea amnicola, that were growing along the banks of the Rio Grande River in Salineño, TX. The first- or second- instar caterpillar appeared extremely thin for its length.

The caterpillar grew quickly. As can be seen in the pictures, its appearance changed with each new instar. The caterpillar pupated on or about 10-15-11, two weeks after it was found. I expected the moth to overwinter in the pupal stage, but it surprised me by emerging on November 3, at most 19 days after it pupated.
