There are 15 articles here , published between June 2026 and June 2026, and they answer questions rather than catalogue species: how to tell two similar things apart, what a particular mark or shape means, what to do once you know. They are the long form.

This section has no interactive key yet. Where a subject splits cleanly on characters an ordinary person can observe, a key beats an article — and where it does not, an article is the honest format. Suggestions for keys that would work are welcome on the contact page.

There is a third thing on the site worth knowing about from here, because it answers a question this section cannot. People arriving at an identification problem usually end up comparing apps, and the honest answer to "which one" depends on facts that change — what each costs this month, what it locks behind a subscription, who publishes it. Those pages exist under compare and alternatives, and not one figure on them is typed by hand: every price and every in-app purchase list is read from a dated App Store snapshot, and the build fails if a currency amount ever appears in the editorial text. It is the same discipline as the numbers below, applied to a subject that goes stale faster.

Reading a shortlist without being fooled by it

Whatever brings you here, the failure mode is the same and it is worth naming. A key, an app and a search all hand you a shortlist, and a shortlist feels like an answer. It is not: it is a set of candidates that survived the characters you happened to check, and the one at the top is usually the one that is common rather than the one that is right. That is often the same thing, which is exactly why it is dangerous when it is not.

Three habits fix most of it. Check a character you have not used yet — if the candidate survives a test drawn from a different part of the organism, the identification is much stronger than one built on colour alone. Check where you are: an enormous share of confident misidentifications are species that do not occur within a thousand miles of the observer, and geography alone settles them. And notice when the answer does not matter — a great many identifications are curiosity, where being wrong costs nothing, and the small number where it does cost something are worth treating completely differently.

Where the consequence of an error is medical — anything eaten, anything that bit somebody, anything a child had in their hands — no page here and no app is the right tool. Describe what you have to somebody qualified, and keep the specimen or a photograph. The keys are built to make that description accurate, which is a genuinely useful thing to be, and it is a different job from telling you it is safe.
