While on a recent photography expedition in the lush Ouachita National Forest of Arkansas, I was lucky enough to spot and photograph an incredible creature – the caterpillar of the elusive Luna Moth. This early life stage of the stunning lime-green Luna Moth is a scarce find indeed.
The caterpillar I discovered was inching its way across a backcountry road, likely in search of deciduous leaves to feed on. Luna Moth Caterpillars are voracious eaters, known to devour the leaves of trees like birch, persimmon, and sweetgum as they prepare for their transformation into the winged beauties we call Luna Moths.
Over the course of its development, the caterpillar will shed its skin several times, growing larger with each molt. Once fully mature, it will spin a silken cocoon and undergo metamorphosis into the adult moth.
The adult Luna Moth is a sight to behold, with lime-green wings spanning up to four inches, marked by eyespots and elegant tails trailing from the hindwings. These moths live for only about one week after emerging from their cocoons in early summer, focused solely on reproducing before their brief lifespan comes to an end.
Spotting a Luna Moth in the wild is exceptionally rare, so to catch a glimpse of the caterpillar phase of this elusive species was a thrilling moment in my photography career. I feel immensely grateful to have captured this image of such an exquisite creature in its natural habitat. It serves as a reminder of the wonders that can be found when exploring our national forests.
During this extraordinary encounter, I relied on my trusty equipment to capture this moment for posterity:
- Camera: Canon EOS R5
- Lens: Canon RF100-500 mm F4.5-7.1 L IS USM

No, Luna Moths are not common in the Ouachita National Forest, and spotting one, especially in its caterpillar stage, is considered a rare and special event.
3. What is the significance of Luna Moth’s tails and eyespots on its wings?
The tails and eyespots on the Luna Moth’s wings are believed to serve as a form of defense against predators. They can confuse potential threats and make the moth appear larger and more intimidating.
4. How can I support wildlife conservation efforts in Arkansas?
Supporting local conservation organizations and adhering to Leave No Trace principles when visiting natural areas can help protect the wildlife and ecosystems of Arkansas.
5. Can I find Luna Moths in other parts of the United States?
Luna Moths are found in various regions of the United States, primarily in the eastern half of the country. However, their sightings are still relatively rare due to their short adult lifespan.
