Hornworm on Spicebush mystery
Last week I brought in a Spicebush (lindera benzoin) leaf that had an egg on it. The egg was larger than a Spicebush Swallowtail egg and was yellowish green. It had hatched yesterday morning and turned out to be some sort of hornworm, very light green with a dark tail.
After watching it wander around for quite awhile in the container, I put some other types of leaves in there to see what it would eat. I put in viburnum dentatum and lentago, wild black cherry, tomato, and honeysuckle.
This morning it's perched along the rib on the back of a v. dentatum leaf. The tip of the leaf has been chewed but it may have been that way when I put it in there and I just didn't notice. It's body is darker than its head now and the tail is still very dark.
Any guesses on what it might be? Are there any hornworms that use spicebush as a host? I couldn't find any with a web search. I'm going to try putting some fresher spicebush leaves in the container and watch to see if it will eat those. Maybe the old leaves were too dried out.
