Puss moth caterpillars, also known as Megalopyge opercularis, are small, venomous caterpillars that boast a furry exterior, often compared to the fur of a kitten. These intriguing creatures have earned their reputation for their painful stings, which can cause severe irritation in humans.

You might be wondering where these caterpillars reside. They can be found primarily in the southern United States, ranging from Texas and Florida to as far north as Maryland. They tend to inhabit a variety of trees and shrubs, where they feed on leaves and continue to grow until they’re ready to transform into an adult flannel moth. So, keep an eye out for these fuzzy critters next time you’re exploring the great outdoors, but remember to steer clear – their innocent appearance can be deceiving!

What Are Puss Moth Caterpillars?

Puss moth caterpillars are the larval stage of the southern flannel moth, also known as Megalopyge opercularis. These caterpillars are notorious for their venomous spines hidden beneath their fuzzy exterior.

Understanding the Puss Moth Caterpillar Life Cycle

The life cycle of a puss moth caterpillar consists of a few stages, including the egg, larval instars, pupa, and adult moth:

  • Egg: Adult moths lay eggs on leaves or other surfaces. These eggs hatch into caterpillars.
  • Larval instars: After hatching, the caterpillars, also known as Italian asp or woolly slug, go through distinct growth stages called instars. With each instar, they shed their skin to accommodate growth.
  • Pupa: The final instar stage leads to the formation of a pupa, where the caterpillar undergoes metamorphosis into an adult moth.
  • Adult moth: The transformed adult moth emerges from the pupa to continue the life cycle.

It is vital to recognize the appearance of the different life stages. Puss moth caterpillars are distinctive, with their soft, furry appearance resembling a small cat’s fur. However, adult moths, such as the southern flannel moth, look quite different, with hairy, flannel-like scales.

Comparing puss moth caterpillars to other common caterpillars like the leopard moth caterpillar reveals some differences:
