Bug Bite Identification Photo Gallery

mosquito bites

Identifying Bug Bites can be a challenge because of how similar they can feel and appear. Everyone has a different immune reaction to being bitten or stung, so the amount of inflammation and level of severity will vary.  

Most bites from common insects will heal quickly and easily, while others may be more painful or require medical care.  

These photos and their descriptions can help you identify insect bites/stings.

mosquito bites

  • Reaction – very itchy and can sting 
  • Location – anywhere, especially exposed skin

"Spider Bites" by chantellervheerden is marked with CC PDM 1.0 

Most spiders are nonvenomous, but there are several poisonous varieties to watch for. We’ve included information about bites from the Black Widow (left) and Brown Recluse (right).  

  • Appearance (nonvenomous) – small red marks or welts  
  • Black Widow – one to two bite marks 
  • Brown Recluse – blister, surrounded by a bruised or red area, then fills with blood and ruptures/scars 
  • Reaction (nonvenomous) – pain around the bite, redness, swelling 
  • Black Widow – sharp pain, redness, swelling, cramping in the torso, nausea, sweating, anxiety, or muscle weakness 
  • Brown Recluse – little to no immediate discomfort, but pain about an hour later, itchiness, nausea, fatigue, chills 
  • Location – anywhere, especially exposed skin 

Here is a resource for more information about dangerous spider bites


tick bite

Tick bites have the potential to transmit Lyme disease as well as other pathogens through their bites. Use bug spray to prevent these bites, especially if hiking.  

  • Appearance – slight swelling or rash 
  • Reaction – minimal reaction, it can be challenging to know if you’ve been bitten unless you catch the tick on you, see that it has dropped off, or discover a bull’s eye-shaped lesion (above) which is a hallmark symptom of Lyme disease 
  • Location – they seek out warm areas on the body, so they frequently bite in the armpits, behind the knees, or on the head/neck 

Fire Ants
