Identify a plant, bird or bug from a description

Help identify what I saw.

Description: [size, colour, where, behaviour]
Photo description if no upload: [details]
Location in UK roughly: [optional]
Season: [optional]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Top likely matches with why.
2. What would confirm or rule each out.
3. Look-alikes that fool people.
4. Reminder: don't touch if it could be harmful.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, steps or official URLs you're not sure of. UK English.
