Before you bend down to take a closer look, you'll want to know what those slithering yellow lines are and why you should run away as fast as possible.


These little yellow lines also could have a different smell to them. If you're smelling cucumbers, you definitely need to get out of there because that yellow tail isn't happy.

Baby Copperheads Unique Yellow Feature

Just like Illinois, copperheads are a poisonous snake that is native to Iowa. According to the Iowa DNR, copperhead snakes are one of 4 venomous snakes in the state. They range from 24 to 26 inches long. These snakes are active during the day in the spring and fall and become nocturnal during the hot summer months.

Before copperheads become mature snakes, mother copperheads give birth in Iowa typically in the springtime, and can produce up to 14 baby copperheads. Baby copperhead snakes have something unique that helps you know where they are: a bright yellow tail.
