	Cecropia Moth Caterpillar

Cecropia Moth Caterpillar
-by Dennis M. Ferraro Extension Educator Douglas/Sarpy Extension Unit

This caterpillar or larvae is the largest found in eastern Nebraska. Over four inches long and almost 3/4 inch in diameter, it is light green with a fluorescent blue overcast. Cecropia caterpillars have several rows of small ball-like spikes called tubercles along their bodies. There are two rows of yellow spikes and two rows of blue ones. A pair of red spikes are located near the head.
This caterpillar feeds on a wide variety of trees and shrubs. It is most commonly found on birch trees. This pest can devour a lot o foliage, but usually appears in small enough numbers that damage is very unlikely.
The larvae forms a dirty gray-colored pupa or cocoon which resembles a pod. This sac, which hangs between branches, is about four to five inches long and an inch or two wide.
No control is needed for cecropia moth caterpillars. They cause no harm to humans, and may be held and examined. They provide an excellent experience with nature for children.
