At the June yard tour, Dave Tylka talked about a caterpillar that ate all the leaves on his Indigo plant last year. I had the same problem, and was surprised to learn I wasn’t alone. The caterpillar belongs to the Broom Moth. I looked them up and learned they can defoliate an indigo in just days.
I took the route of removing the caterpillars and cutting down the Indigo they had chosen as a food source. My decision was based on the fact that I have a number of different Indigos, and did not want them all defoliated. This year the Indigo I cut down came back with no ill effects. I will keep a look out and update this blog if I get a repeat experience this year.
