Unidentified; likely an insect bite or skin irritation

The insect is not visible; the photo shows reddened skin near the ear and neck.

Not determinable; no identifiable insect is shown.

The reddish spots could result from a mosquito, flea, bed bug, mite, or other arthropod, but appearance alone cannot identify the cause.

Monitor for spreading redness, increasing pain, warmth, swelling, pus, fever, breathing difficulty, or facial swelling; seek medical care urgently for severe symptoms. Avoid scratching and consider medical advice if lesions persist or multiply.
