To identify the insect responsible for a bite, one must be familiar with the appearance and symptoms of common bites, explains Everyday Health. If someone exhibits symptoms of a venomous bite, it is important to seek medical attention to confirm the source of the bite and receive proper treatment.
Mosquito bites are common and present as round, pink or red bumps on the skin that itch, notes Everyday Health. Although mosquito bites are not typically dangerous, they sometimes transmit West Nile Virus. Symptoms of this virus appear between five and 15 days following the bite and include fever, headaches and body aches. A skin rash and swollen glands also sometimes occur. In extreme cases, West Nile Virus causes the development of encephalitis, some of the symptoms of which include neck stiffness, convulsions and disorientation.
Some signs of a non-venomous spider bite are skin swelling, reddened skin and pain, although it is possible to suffer an allergic reaction to a non-venomous spider bite and experience symptoms such as difficulty breathing, chest tightness and facial swelling, explains Everyday Health.
Two types of venomous spider bites are those of the black widow spider and the brown recluse spider. About 30 minutes following a black widow bite, one typically experiences some pain and swelling. Within eight hours, other symptoms that can develop are back pain, abdominal pain, muscle pain or rigidity, nausea and vomiting. About four to eight hours after occurring, brown recluse bites look similar to bruises or blisters with bluish-purple coloration surrounding the bite. People sometimes experience a sharp pain when bitten by a brown recluse, but others do not notice the initial bite, notes Everyday Health.
