The Occurrence of Dark Spots as a Result of Insect Bites
Most people, especially adults, tend to have very minimal reaction to insect bites. Mosquito bites, for instance, are usually harmless, but can leave a puffy, reddish bump on the skin. These bumps do go away on their own in a few hours or days, provided they don’t get infected. In some cases, however, a mosquito bite can also manifest as dark or black spots.
