WebMD and Everyday Health both provide slideshows displaying photos of insect bites with helpful information to enable identification of the biting insect based on the appearance of the bite. While some insect bites are just annoying, others have the potential to transmit serious diseases, as WebMD explains.
Mosquito bites manifest as small, itchy red bumps on the skin, as Everyday Health explains. Bed bug bites tend to cluster together, often in rows, in an angry, inflamed red rash. Spider bites tend to raise a significant swollen welt that often turns red. The bite of the brown recluse spider often has a bluish tinge.
Tick bites sometimes still contain the tick in them; ticks must be properly removed for safety. Lyme ticks leave a rash that looks like a target, with a large red circle surrounding the smaller red bite, according to WebMD.
