Moths as Pollinators? Yes!


By Paul James

Last week was National Moth Week. I’m sure you knew that already. But why in the world am I writing about moths? Well, despite the fact that butterflies get all the great press (deservedly so) and bees are hailed as the most precious of pollinators (likewise, deservedly so), it turns out that there are far more moths on the planet than butterflies, and moths are actually more efficient pollinators than bees. Who knew?!
 

Moths vs. Butterflies -- What’s the Diff?

Moths:
  • Feathered, comb-like antennae
  • Rest with wings folded flat
  • Short and plump bodies and legs
  • Dull or camouflaged wings
  • Pupate in cocoon
  • 170,000 species worldwide
Butterflies:
  • Club-like antennae
  • Rest with wings folded together
  • Long and thin bodies and legs
  • Brightly colored wings
  • Pupate in chrysalis
  • 17,500 species worldwide
Most (but not all) moths also tend to work the night shift, whereas butterflies flutter about during the day.
 

Accidental Pollinators

Neither butterflies or moths pollinate plants intentionally. They’re simply seeking nectar, and in the process pollen winds up attached to their legs or body or proboscis and is transferred inadvertently from one flower to the next. Moths are mostly attracted to white or dull-colored flowers that are highly fragrant. They’re especially fond of Datura, Gardenia, honeysuckle, morning glory, Nicotiana, Tuberose, and Yucca (see below).
 
The Yucca moth, found throughout North America, is the only pollinator of a perennial grass known as soapweed. Their relationship is codependent -- the plant needs the moth and the moth needs the plant.
 

Moths as Pests

Not all moths are welcome. In the house, clothes moths can be troublesome and destructive, eating animal-derived fabrics such as wool, fur, silk, and leather. Traps (available online) are your best defense. In the garden, the larval form of several moths can be particularly destructive, especially armyworms, tobacco hornworms, cabbage loopers, corn earworms, and cutworms. Bt, an all-natural biological insecticide, does a great job of controlling them.
 
For every species of butterflies worldwide, there are 19 species of moths.
 

No Mothballs!

Yes, you can still find folks who recommend mothballs to repel rodents, squirrels, bats, and snakes, but they don’t work. Moreover, they can contaminate soil and water, and pose a threat to young children and pets. Their active ingredients, whether naphthalene or paradichlorobenzene, are toxic.
 

Lights Out, Please!

If you rely on outdoor lighting for security, consider using motion-sensor lights only. Bright light at night seems to attract and disorient moths (there are conflicting theories as to why), making them vulnerable to bats.
 
The puss moth caterpillar has spines attached to venom sacs. Contact causes extreme pain (and other nasty symptoms) that may last up to a week.
 

The Cool Moths of Oklahoma

Sphinx Moths and Hawk Moths (numerous species) are awesome, and with wingspans of up to three inches, they’re two of the largest moths in North America. They pollinate both day and night, being attracted to cardinal flowers, Columbine, primrose, honeysuckle, lilac, penstemon, and phlox. Both species produce the rather ominous-looking but harmless tomato hornworm caterpillars, which are anything but harmless to tomatoes. Handpicking is the best control method.
 

Hummingbird Moths

Hummingbird Moths are relatives of Sphinx Moths, and are so named because they hover in the air over flowers, using their long tongues to probe for nectar and looking remarkably similar to hummingbirds. They flock to honeysuckle, bee balm clovers, phlox, thistles, and vetches.
 

Luna Moth

This is an almost indescribable beauty with its enormous wingspan (up to five inches!), distinctive emerald green color, and unmistakable “tails.” Once you see one, you’ll never forget it. In fact, it was a Luna Moth that prompted my interest in entomology as a kid. It’s about as cool as they come.

Fact is, there are dozens of really cool moths in Oklahoma. Among my favorites are the Abbreviated Button Slug Moth, the Beautiful Wood Nymph, and the Bird Dropping Moth (yep, it lives up to its name). To see them in all their splendor, check out this site:

Darwin’s Giant Hawk Moth

The Giant Hawk Moth was discovered in Madagascar in 1882. But its existence was predicted by Charles Darwin 20 years earlier and 5,700 miles away. While examining a Star of Bethlehem orchid, Darwin noticed its foot-long nectar spur and wondered what could possibly reach the pool or nectar at the bottom. He wrote to a friend, asking “What insect can suck it?” He predicted that one day scientists would discover the orchid’s partner, and two decades later they did just that, documenting a subspecies of African Hawkmoth with a foot-long proboscis.
 

Events

Speaking of things that creep in the night, our Southwood Home & Garden location on the corner of 11th and Lewis is getting an eerie facelift, and you're invited to the unveiling! Join us on the evening of Saturday, August 10, at 6 p.m. as we kick off our new Bootique with a night of tricks, treats, music, and Halloween galore. The location will temporarily close until the night of the unveiling as we prepare the scares.
 
Back to School Make-n-Take Workshop

Saturday, August 17, 10 - 11:30 A.M.
It's already time to send the kiddos back to school 😱 Start the school year with a bloom at our Back to School Make-n-Take Workshop, where you and your kids can create a beautiful potted houseplant arrangement to give to their teachers (or keep for yourselves!). All supplies are provided, but spots are limited to 25 tickets. If you want to make more than one arrangement, or if you have multiple children who want to create arrangements for their teachers, please buy the according amount of tickets. Get yours at https://southwoodgardencenter.com/event/back-to-school/
 
Tip Of The Week

Moths and butterflies need moisture and minerals. To provide both, put a handful of dirt in a saucer, add water to make a loose slurry, then place a few small rocks here and there to serve as landing pads.
