Insect bites or stings may be associated with large circular areas of swelling; the raw areas on the left lesion are probably due to scratching. Some people react to insect bites with large, fluid-filled blisters. On people with darker skin, inflammation and redness from insect bites can appear as red-brown-colored lesions. Insect bites or bug bites can cause localized redness and itching. An insect bite can result in a blister. Two insect bites are shown on this foot; note that the larger one has a tiny central crust where the insect bit. Insect bites often have small blisters that dry and crust. Bites from insects often lead to itch, scratching, and resulting crusts. Bug bites often cause hive-like (urticarial), swollen lesions.
