Submit a bug!

WELCOME TO R/WHATSTHISBUG!

Got a photo of a bug you'd like identified? Submit it here and we'll try to figure it out! Best view for ID is top-down, well-lit, low-contrast photos. Pictures are preferable to videos for ID requests but we'll work with what you have.

I don't need an ID, but can I share a cool bug? Yes! This subreddit is also a community for any arthropodic discussion. But remember, every ID is needed! If you know the identity of your bug, do share it with the community!

Can I submit a dead bug for ID? Yes, but please bear in mind it’s always easier to ID living specimens. While we realize that extermination is sometimes necessary, comments promoting gratuitous violence against arthropods, or causing unnecessary suffering, (“kill it with fire” etc) will be removed. Linking to subs that explicitly promote hatred is not allowed.

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.

SUBMISSION GUIDELINES

• Indicate the geographic location.

• Take the clearest and most detailed photo possible. Videos are OK, but pictures are best for IDing.

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

• Provide any other information you feel could help! If you could not take a photo of the bug, a detailed description (or even a drawing) may work.

IDing GUIDELINES

• Cite/Link a source whenever possible. Our "ID Guides" section below has some good ones. A search engine result page is not enough.

• 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.

• ID guides tend to be regional. While BugGuide.Net 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.
