Life Cycle and Behavior

Eggs to Larvae

  • Heiroglyphic moth: Lays eggs on plants
  • Larvae: Hatch after a short period

The Heiroglyphic moth begins its life cycle by laying eggs on host plants. Soon after, tiny larvae hatch from these eggs and start feeding on the plant’s leaves.


  • Feeding: Leaves of various plants
  • Silk: Produced for pupation
  • Growth: Molts multiple times

Caterpillars are the larval stage of the Heiroglyphic moth. They feed on the leaves of various plants to grow. During this stage, they produce silk, which helps them find a secure spot for pupation. As they grow, caterpillars molt multiple times before transforming into pupae.

Pupa to Adult

  • Pupation: Secure spot using silk
  • Transformation: Metamorphosis into adult moth
  • Adult behavior: Nocturnal and attracted to light

Heiroglyphic moth caterpillars find a secure spot using their silk to pupate. In this stage, they undergo metamorphosis and transform into adult moths. As adults, these moths are nocturnal creatures and are attracted to light sources at night.

Stage Characteristics Duration
Eggs Laid on plants Short period
Caterpillars Feeding, silk production Multiple molts
Pupa Secure spot, metamorphosis Varies
Adult Nocturnal, attracted to light Typical moth lifespan
  • Pros:

    1. Variety of host plants for caterpillars
    2. Silk production allows for secure pupation
  • Cons:

    1. Attraction to light may lead to danger
    2. Caterpillar feeding may damage host plants

Host Plants and Plant Species

Common Host Plants

The hieroglyphic moth can be found on a wide array of plant species. They often occur on:

  • Soybeans (Glycine max)
  • Sida sp.
  • Phyllanthus latifolius
  • Boerhaavia diffusa
  • Morongia leptoclada
  • Carya sp. (pecan)
  • Ipomoea batatas (sweet potato)
  • Cocos sp. (coconut palms)
  • Casuarina equisetifolia
  • Corchorus hirsutus
  • Lippia alba
  • Solanum sp. 1

Additionally, some of the moth’s preferred host plants include:

  • Melochia corchorifolia
  • Melochia tomentosa
  • Waltheria indica
  • Lespedeza thunbergii
  • Schrankia portoricensis
  • Malvastrum spicatum 1

Feeding Behavior

Hieroglyphic moth larvae have a unique feeding behavior. They feed gregariously, meaning they feed together in groups 1. This characteristic can lead to the moth larvae being considered pests when they feed on certain plants such as pecan, coconut palms, sweet potato, and soybeans 1.

In the United States, these moths are distributed throughout Florida and other tropical or subtropical regions1. Since they can feed on various plant species, their presence can impact a variety of local ecosystems and industries.

Predators, Pests and Parasites

Natural Enemies

The Heiroglyphic Moth faces several natural enemies in its environment. Some common predators that prey on the Heiroglyphic Moth and its larvae include:

  • Arthropods: Various arthropod species feed on moth larvae and adult moths.
  • Noctuoidea: Within the broader moth family, some noctuoidea species may prey on Heiroglyphic Moth larvae.
  • Parasitic wasp: These wasps lay their eggs inside caterpillars, eventually killing the host.

Economic Impact on Agriculture

Heiroglyphic Moths can have both beneficial and detrimental impacts on agriculture, depending on the situation. Here are some examples of their effects:

  • Pros

    • They can contribute to pollination, helping plants reproduce.
    • Their larvae can help keep certain plant populations in check by feeding on them.
  • Cons

    • In some cases, their larvae can cause damage to certain crops by feeding on leaves and stems.
    • Large populations of Heiroglyphic Moths might lead to an imbalance in the agricultural ecosystem.
Benefits Drawbacks
Contribution to pollination Potential crop damage
Control of certain plant populations Possible ecosystem imbalance

Overall, understanding the behavior of the Heiroglyphic Moth and its interactions with other species in their ecosystem is crucial for proper pest management in agriculture.

I’ve looked thru WhatsThatBug.com’s Tiger Moth section, and think that this might be a Tiger Moth? But not sure what type. We live near Myrtle Beach, SC, and found this little guy right on our front porch this afternoon. And right above the front door was a baby mantis. We had a little Wild Kingdom going on. I just love days like that, when they show up right on your front porch, just begging to have their picture taken!

Hello Mr.Bugman! My brother told me about your page after I asked him if he had ever seen the bug in my picture. My name is Brittany, I work at a self storage facility out in the middle of nowhere. Every morning as I check the property and there are so many bugs outside. I think they must be attracted by the lights on the property at night. I always take pictures if i find new ones for my “collection”. I can normally identity them via google but this one has me stumped! This i am guessing was some type of moth, as after i took the picture he/she flew away. I know you are a busy bugman but I would love to find out what this beautiful somthing was. Thank you for your time!

Hi Daniel!
I found this little guy (about an inch and a half) in the walls of my university. I’ve never seen one like this. It caught my attention because I mistook it for a beetle, upon closer look I realized it was a moth with its wings closed. The pattern is very pretty, almost art nouveau. Do you have any clue on this guy?
