Lonestar ticks can be found in PA but are generally more common in the southeastern U.S. Females are easily identifiable with a yellow-white dot on their backs, while males lack this feature and appear to have a reddish-brown appearance. These ticks are most known for causing Alpha-gal Syndrome. This allergy can potentially occur from tick bites, as the alpha-gal molecule is in their saliva. Not everyone who is bitten by these ticks will develop Alpha-gal Syndrome. For more information on tick identification and Lonestar ticks, visit: https://www.ticklab.org/lone-star-tick
