Don’t pet this cute but venomous caterpillars in Texas

Fall is the season for changing temperatures, falling leaves and the start of the holidays. It’s also a time when cute, fuzzy caterpillars come out in Texas. But don’t let their cuteness fool you. The creatures have potent spines that release a venom that can send you to an emergency room.

The Texas southern flannel moth, also known as an asp caterpillar, typically makes an appearance around the area between Halloween and Thanksgiving, Texas A&M AgriLife Extension Service previously told MySA. During the late spring or early summer, adult puss moths will emerge and lay several hundred eggs on favored host trees. While asp caterpillars can be seen year-round, the largest generation typically appears in the fall and winter. 

And, they are being sighted already.

Ranger Eric with Lake Livingston State Park posted a video on Facebook of the caterpillar stage of the southern flannel moth. He said he had never seen them before and acknowledged the critter’s beauty. However, Ranger Eric also mentioned the venom. Beneath its soft, hair-like fuzz lie venomous spines that can cause severe reactions in humans. Venom effects can include immediate, intense pain (often compared to a broken bone or bee sting), swelling, redness, nausea, and headache. 

“So definitely appreciate these without touching or picking them up in order to avoid being stung,” Ranger Eric mentioned in the video posted on November 8.

Sheldon Lake State Park & Environmental Learning Center also posted on Facebook about the cute caterpillar on Friday, November 14. The staff warned others about the venom and provided some tips for those who have been stung. 

“Please remember to treat all wildlife with respect when you visit their home. Keep a safe distance and do not handle them for your safety, and theirs,” the center stated.
