Finding a tiny insect crawling on your child after a walk in the woods can be alarming—especially when it looks like a tick and has a noticeable white marking on its back.
The good news is that the white spot itself is not something mysterious or unusual. In fact, it can be an important identification feature.
Could It Be a Lone Star Tick?
Based on the appearance in the photo, the insect looks consistent with a tick, and the prominent white spot is characteristic of an adult female lone star tick (Amblyomma americanum). The CDC identifies the distinctive white “lone star” on the back as a key feature of this species.
However, a photograph alone isn’t enough to confirm the species with certainty. Tick identification can depend on details such as the tick’s size, life stage, markings, and geographic location.
Why Does This Tick Have a White Spot?
The white marking is a natural part of the tick’s body. It isn’t a parasite, egg, or unusual growth.
The adult female lone star tick is particularly recognizable because of this single pale spot on the shield-like area of its back.
This is where the name “lone star tick” comes from.
