Have you found a strange bug or a new plant in your garden, or stumbled across an intriguing animal bone or fossil while out on a country walk? Let us help you find out about it.
The dedicated team at the Museum's Identification and Advisory Service can answer your queries about insects, fossils, plants and other wildlife and natural history specimens found in the UK.
You can also use our online tools and resources to identify UK plants and animals, and learn more about them.
Four ways to identify your specimens and sightings
1. Check our selection of ID guides to see if one is relevant. The Museum has also produced a free tree identification app for iPhone, Leafsnap UK.
2. Upload your photos and descriptions to our online identification forums for help from our scientists and other naturalists. Please tell us as much about your specimen as possible, including a detailed description, where and when you saw it, and its approximate size.
3. Post your specimen or photographs to:
Identification and Advisory Service
Natural History Museum

4. Visit the Centre for UK Biodiversity at the Museum and show your wildlife or geology specimen to a member of our ID team. Drop in between 10.00-12.00 and 14.00-16.00:
- Monday to Friday
- the first Saturday of the month (or the second Saturday after bank holiday weekends)
