Within the Sphingidae family, pink-spotted hawkmoths are classified under Subfamily Sphinginae and Tribe Sphingini. Their scientific name is Agrius cingulata, with the genus being Agrius.

Life Cycle


The pink-spotted hawkmoth begins its life as an egg, laid by the adult female moth. These eggs are typically laid on the leaves of host plants, such as Datura and other plant species. The development process is generally brief, hatching in about one week.


Once hatched, the larvae (caterpillars) emerge and immediately start feeding on the leaves of their host plants. Pink-spotted hawkmoth caterpillars are known for their voracious appetites. The larvae undergo several growth stages known as instars, with each shedding its skin to accommodate its size increase. They complete these stages in just a few weeks.


Upon reaching their final growth stage, the pink-spotted hawkmoth larvae enter the pupal phase. During this phase, the caterpillars spin a cocoon and transform into a pupa. The transformation takes a varying duration, typically several weeks, depending on the climate and season.

Adult Moth

The final stage of the pink-spotted hawkmoth’s life cycle is the emergence of the adult moth. As adult moths, their primary purpose is to mate and lay eggs, ensuring the continuation of the species. Adult pink-spotted hawkmoths are known for their distinctive wing markings and long proboscis, which they use to feed on nectar from flowers during nighttime hours. Mating occurs during the warmer months, and the adult moths have a relatively short lifespan, often living only a few weeks to a month.

Feeding and Diet

Larval Food Sources

The larvae of the pink-spotted hawkmoth, also known as the sweetpotato hornworm, primarily feed on plants from the Convolvulaceae and Solanaceae families. Some examples include:

  • Datura species (moonflower)
  • Ipomoea species (morning glories)
  • Petunia species (petunias)

These plants provide essential nutrients for the pink-spotted hawkmoth larvae to grow and develop.

Adult Food Sources

As adults, pink-spotted hawkmoths feed on nectar from various flowers. They have a preference for sucrose over fructose and glucose, which provides them with energy for flight and reproduction.

Common nectar-rich flowers that pink-spotted hawkmoths visit include:

  • Sweet potato flowers (Ipomoea batatas)
  • Moonflowers (Datura species)
  • Morning glories (Ipomoea species)
  • Petunias (Petunia species)
Nectar Source Plant Family Flower Type
Sweet potato Convolvulaceae Orange/Yellow
Moonflower Solanaceae White
Morning glories Convolvulaceae Various colors
Petunias Solanaceae Various colors

By visiting flowers and feeding on nectar, adult pink-spotted hawkmoths play a vital role in the pollination of these plants, ensuring their survival and reproduction.

Relationship with Humans

Hawk Moths as Pollinators

Pink-spotted hawkmoths are part of the hawk moth family, which are known to be important pollinators. They have a long proboscis to feed on nectar from flowers, often hovering near them. Naturalists can observe these fascinating creatures in open areas where flowers are abundant.

Some key features of hawk moths as pollinators include:

  • Long proboscis for nectar feeding
  • Hovering near flowers
  • Active in open areas with abundant flowers

Pink Spotted Hawkmoths as Pests

While some hawk moths like Manduca rustica do not cause significant problems, pink-spotted hawkmoths have been observed as pests in the U.S.. They can cause damage to plants and crops by laying eggs on them, with the larvae then feeding on the plant material.

Pros of pink-spotted hawkmoths:

  1. Good day. I found one of these in my back yard and it’s a beautiful specimen. Do they normally travel in the Southern California area?

  2. RE: Honolulu, HI hawk moth caterpillars. I have many of the same on my Morning Glories in Kaimuki near Kapahulu 1.jpeg/Users/MariaMcClellan/Desktop/securedownload.jpeg

  4. just found the same caterpillar in my sweet potato bucket! Looked it up and found your image- same markings as the one you posted- green with brown markings like twigs down the sides! What did you do with yours? We don’t know whether it will form a chrysalis or if it is poisonous!

    • According to Sphingidae of the Americas: “Larvae feed on plants in the Convolvulaceae family, especially Ipomoea batatas (sweet potato) and in the Solanaceae family, especially (Datura) (jimsonweed) and related plants in the Americas.” According to BugGuide: “Larvae feed on Sweetpotato (Ipomoea batatas), jimsonweed (Datura spp.), pawpaw (Asimina spp.), and other plants in the Potato (Solanaceae) and Morning-glory (Convolvulaceae) families.” If you found the caterpillar on a palm, it was either a different species or it was not feeding.

  5. Hi everyone we found one in our sweet potatoes patch. They are creepy looking and was worried about it attacking us in the middle of the night while we sleep, but after reading a few comments we will out it back in the yard to pupate.

  6. We found this same looking caterpillar under our doorstep after the heavy rains…my daughter google imaged it and that’s how we found out what it was. We found it on 1/15 and I took it to school for my 3rd graders to witness the cycles and to learn about it. As of today 1/21 he is now in his cocoon and hopefully in 10 days we can witness it transforming !! My class is so excited as they have never seen anything like it, nor have I! What a great learning opportunity we have been blessed with to witness !!

  7. Found on Big Island 8 miles outside of Pahoa in Puna District.
    We love our sweet potatoes and choose to feed it to the chickens.

  8. I found a few of these horn worms on my morning glory plants a couple of weeks ago. It took a while to find an identification of them where I live as I believe they are more typically found in southern US. I live in New Hampshire and we were having pretty cold nights already. I re-homed a couple of them indoors right before they were entering their pupa phase. They’ve done really well and just formed their pupa where they will stay over winter. Looking forward to seeing them transform in the spring!
