Submit a bug!


Got a photo of a bug you'd like identified? Submit it here and we'll try to figure it out!

I don't need an ID, but can I share a cool bug? Yes! This subreddit is also a community for any arthropodic discussion.

Before you post, we are not going to kill it with fire, so don't ask!

Refrain from posting bites unless you saw the bug biting the person. We CANNOT diagnose injuries or identify insects/spiders that allegedly caused bites. Seek medical advice before our advice if you didn't see a bug biting you.

If your submission does not appear in the "NEW" bucket, message the mods to check the spam filter.


  • Indicate the geographic location.

  • Take the clearest and most detailed photo possible.

  • Indicate the size excluding antennae - the more precise the better.

  • Provide any other information you feel could help!


  • ID guides tend to be regional. While is popular, it only pertains to arthropods in the U.S. and Canada. For bugs outside the U.S. and Canada, try to search for a guide specific to that region. For example, if you want to ID a butterfly from Brazil, this would be a great guide.

  • In, click on the "Browse" tab to switch to an ID-friendly, taxonomic view.

  • Don't make blind/random guesses. Our goal is to provide positive leads; false leads are counter-productive, e.g. "similar looking" is rarely good enough at the species level. If one is unfamiliar with the taxon, practice diligence, e.g. check other members of the taxon, as well as those of higher taxa. Especially for medically significant bugs, if you aren't 100% sure, leave the ID to someone more knowledgeable.

  • Cite/Link a source whenever possible.
