Yes they do... they burrow inside the bags & sometimes the rice bags look more their color than the color of the rice. They’re one of the two types of bugs I’m disgusted by XD.
Oh i have 2 kill those b/c my mom is radically afraid of them. I learned this the hard way when i simply picked up a big spider and brought it to my mom at age 4, saying “Look what i found, Mom!” That didn’t go over well lol
One time i had a pet cattapilar and i used to bring it to school and we decided to let it live in the playgruond the next i saw it squished on the blacktop XD >:'(
