Throughout history, people have developed instincts and a deep understanding of which animals to avoid. While most creatures pose little to no danger, it’s essential to stay cautious in nature, especially around unfamiliar animals.
Leslie Howe, a mom from Georgia, experienced this firsthand during a family outing to a small local park in 2014. What began as a typical day with her children soon took an unexpected turn when she noticed an unusual creature that looked like a small, furry ball. This strange sight immediately made Leslie feel uneasy—a gut feeling that proved wise.
The seemingly harmless creature Leslie spotted was a Megalopyge opercularis larva, commonly known as the “puss caterpillar.” Despite its soft, cat-like fur, the puss caterpillar conceals venomous spines that can cause a painful sting. Leslie’s encounter with the caterpillar serves as a warning for other parents to stay vigilant around these furry-looking insects that may appear harmless.
Experts have noted that the puss caterpillar, found in various parts of the United States, feasts on foliage in states from New Jersey to Florida and as far west as Texas. Reaching just over an inch in length, these caterpillars are easy to overlook, yet the pain from their sting can be extreme. NPR reports that these caterpillars are most commonly found in wooded areas, which may overlap with parks and playgrounds, making caution especially important.
The puss caterpillar’s sting can be worse than a wasp sting, as it injects venom through hidden, toxic bristles in its fur. Leslie’s instinct to steer her children away likely saved them from a severe sting. People who have been stung by this caterpillar report immediate pain that can intensify, spreading through the body. Depending on where the bristles make contact, some have even felt the pain radiate to their bones and last for up to twelve hours.
Don Hall, an ethnologist from the University of Florida, told National Geographic that stings from the puss caterpillar can cause “intense, burning pain” that may require hours to subside. Eric Day, a Virginia Tech entomologist, also experienced the sting while gardening, noting that it left him with a burning sensation and skin irritation that lingered for weeks.
If you or someone you know gets stung by a puss caterpillar, there are a few steps to take for relief. Experts recommend using tape to remove the venomous spines from the skin. Afterward, gently wash the area with soap and water. Applying hydrocortisone cream or baking soda paste can help alleviate itching, but if symptoms worsen, it’s best to seek medical attention.
While stings from puss caterpillars are rarely life-threatening, they can sometimes trigger severe allergic reactions like anaphylaxis, a potentially dangerous condition. Awareness and caution can go a long way to prevent accidental stings from these unusual caterpillars, especially in areas where children play.
