We're reaching into the archives for today's #BenInNature update presented by our friends at Carter Bank & Trust! The following post was originally published on June 18, 2020.

One of my favorite things about this time of year is the wide variety of beautiful moths that are drawn in by my porch light. This moth is Amorpha juglandis, the walnut sphinx moth, and it can be found in deciduous forests east of the Rocky Mountains.

As adults, these moths do not eat and are mainly active during the early hours of the night. The caterpillars eat the leaves of a variety of trees, including not only walnut, but also alder, hickory, beech, hazelnut, and butternut.

One of the neatest features of the walnut sphinx caterpillar is its defense mechanism. If the caterpillar is attacked by a bird, it expels air from two spiracles (openings in an insect's exoskeleton) in its abdomen, which produces a high-pitched squeaking noise! This startles the bird and can cause it to leave the caterpillar alone.

And hey, who among us hasn't been startled and suddenly expelled air from ... you know what, never mind, we'll just leave it at that.

Thank you to VMNH Associate Curator of Invertebrate Zoology Dr. Kal Ivanov for confirming my ID!
