I noticed a bug bite on my leg today. It's surprising to me because I thought it was currently too cold for mosquitos to live. Where I live, we do frequently get mosquitos in the summer, but not typically when it's this cold.
Also, the bite is in a unique spot. It's right below my knee. they typically prefer my hands/arms or my ankles.
All the tic bites I’ve seen in person have a sort of necrotic divot in the center, even if the tic tests negative for disease.
