Just to let you know of a new website feature:

You can now click on the Bradley and Fletcher 'Code' number on the What's on the wing tonight page and see the species distribution and flight plan.

You can also add distribution maps to posts on our latest sightings here (or any website page) by using the simple markup:

The data is pretty much up to date and we will endeavour to keep it so.  All species, macro and micro are included.

You can also render an adult flight period chart using the markup:

[[flight:species name]]

For example [[flight:Convolvulus Hawk-moth]] will show as:

The technology for doing all this was originated by and funded by the Essex Field Club .
