A number of county moth groups now have a "what's flying tonight" feature, which shows the species you are most likely to encounter through the year. This can be enormously helpful in trying to narrow down the choices when you are learning to identify moths.

For Berkshire you can download Moths by Month (NEW VERSION, 487 kb pdf file), which lists the moths most likely to be seen each month through the year, and gives a link to the photos and further information at UKmoths.

Try out these other sites as well - although they are some distance away from Berkshire, their lists still have a lot in common with ours for the commoner species:

• Flight arrivals (NorfolkMoths.co.uk)
• What's on the wing tonight (Somerset Moth Group)
• What's flying tonight (Suffolk Moth Group)
• Current field tips (Suffolk Moth Group - hints and tips for finding moths, especially caterpillars, in the wild)
