What happens if a saddleback caterpillar stings you?

Answered by Jason Smith

If you happen to come into contact with a saddleback caterpillar and it stings you, you are in for quite an unpleasant experience. The saddleback caterpillar, also known as the Acharia stimulea, possesses hollow poisonous hairs or spines that are connected to underlying poison glands. These hairs are the culprit behind the burning sensation and inflammation that follow a sting, which can be as painful as a bee sting.

Upon contact with the skin, the saddleback caterpillar’s poisonous hairs break off and release their venom. The venom contains toxins that cause irritation and trigger an immune response in the body. The initial reaction is usually a sharp, intense pain at the site of the sting. The affected area may become red, swollen, and develop a raised bump. The pain can be quite persistent and may last for a day or two.

In addition to the local pain and inflammation, some individuals may also experience systemic symptoms after a saddleback caterpillar sting. These symptoms can vary from person to person but commonly include nausea, vomiting, and general feelings of malaise. These systemic symptoms usually occur within the first few hours following the sting and may last for a short period of time.

It is important to note that the severity of the reaction to a saddleback caterpillar sting can vary depending on factors such as the individual’s sensitivity to toxins, the number of spines that penetrate the skin, and the location of the sting. Some people may have a stronger reaction than others, and those who are more sensitive may experience more intense symptoms.

To alleviate the discomfort caused by a saddleback caterpillar sting, there are a few steps you can take. First and foremost, it is advisable to remove any spines or hairs that may still be embedded in the skin. This can be done by gently using adhesive tape to lift them off or by using a pair of tweezers to carefully pluck them out. However, be cautious not to break the spines further and release more venom.

Applying a cold compress or ice pack to the affected area can help reduce swelling and provide some relief from the pain. Over-the-counter pain relievers like ibuprofen or acetaminophen can also be taken to alleviate discomfort. It is recommended to avoid scratching or rubbing the sting area as it may worsen the irritation.

If the symptoms persist or worsen, it is advisable to seek medical attention. A healthcare professional may recommend topical treatments or prescribe medications to help alleviate the symptoms and speed up the healing process.

A saddleback caterpillar sting can be a rather unpleasant experience. Contact with the caterpillar’s poisonous hairs can cause a burning sensation, inflammation, and pain similar to a bee sting. Additionally, nausea and systemic symptoms may occur in some individuals. Taking prompt steps to remove any spines, applying cold compresses, and using pain relievers can help alleviate the discomfort. However, if symptoms persist or worsen, seeking medical attention is recommended.
