Key takeaways
- A bug bite identifier is useful for everyday bites; it is not a substitute for medical care for spreading redness, fever, or a stuck tick.
- Tick bites are the highest-stakes category — photograph the tick (not just the bite) before removing if at all possible.
- The same identifier model also helps with the source insect if you can photograph it — bedbug vs cockroach, spider species, ant species.
Quick Answer
[BugLens](https://apps.apple.com/us/app/insect-world-bug-identifier/id6764203982) is a free GradFlowLab iOS app that identifies common bug bites and the insects that cause them from a photo. It is useful for the everyday "what bit me last night" question. It is not a substitute for medical care when symptoms are spreading.
What the App Identifies
For bites:
- Mosquito
- Bedbug (single, line, or cluster patterns)
- Flea (commonly ankle/lower leg)
- Tick (with photo of the tick where possible)
- Common spiders (regional, including some medically significant)
- Ant species
- Wasp/hornet/bee stings (different mechanism, similar identification flow)
For the source insect itself, photographed alone:
- Bedbug vs cockroach (the most-asked confusion)
- Tick species (deer tick / black-legged, lone star, dog tick)
- Spider species
- Common pest ants
When to Use the App and When to Skip It
Use the app for:
- A bite or cluster you noticed in the morning with no other symptoms
- An insect you found in the house and want to identify before deciding whether it is a pest issue
- A tick you have removed (photograph it before disposing of it)
Skip the app and call a clinic for:
- A target/bullseye shape around any bite (possible Lyme)
- A tick that has been attached more than 24 hours (or any uncertainty about time)
- Spreading redness, warmth, or red streaks
- Fever, chills, joint pain following a bite
- Difficulty breathing, throat tightness, or swelling beyond the bite site
The app's job is to triage common cases. It is not the right tool when the situation is already medical.
Photo Tips
- Daylight or bright indoor light, not phone flash
- Close enough that the bite/insect fills the frame
- A coin or fingertip for scale where possible
- For ticks: photograph before removal; keep the tick in a sealed bag after

Try It
Get [BugLens on the App Store](https://apps.apple.com/us/app/insect-world-bug-identifier/id6764203982). Like Snake ID, the value is having it installed *before* you need it. The first night you wake up to a row of three bites in a line is not the moment you want to be searching the App Store.
Frequently asked questions
Can a photo really tell what bit me?
Often yes for common cases — mosquito, flea, bedbug, common spider, common tick. Less reliably for unusual cases or when the bite is older than 24 hours and inflammation has spread. The app's value is in the common cases at hour zero.
When should I see a doctor instead?
Spreading redness, fever, joint pain, a target/bullseye shape, a tick that has been attached more than 24 hours, severe swelling beyond the bite site, or any difficulty breathing. Use the app for triage on minor bites; do not use it as a stall on serious symptoms.
Does it work for the insect itself, not just the bite?
Yes. The same model identifies many of the source insects from a photo — bedbug, cockroach, common ticks, common spiders, ant species. Useful when you find the bug and want to know whether it bites at all.
