As caterpillars, they tend to feed on a wide range of host plants. This includes oak, apple, birch, willow, hackberry, cherry and coniferous trees such as fir and spruce.
The caterpillars grow to about 25 mm long. In color, they vary from light green to a dark brownish green. Light green caterpillars have white lines running down the body from the head to the tip of the abdomen while the darker caterpillars have a black stripe the length of their back.
They have two large dark-green to black tubercles on the second thoracic segment and three rows of smaller spines, or setae, on each side of their body. [ 2 ] [ 3 ] The larvae undergo their first molt around 6–11 days after hatching, their second molt approximately 12 days after hatching, and their third molt around 19 days post hatching. [ 2 ]
