Here in northern Tanzania we are experiencing a huge [westward butterfly migration](http://safari-ecology.blogspot.com/) - originally those of us who saw it thought it was local but it turns out that it's very widespread. We're getting informal reports from all over, but would like to (quickly!) set up a way for people to report sightings:

* A clickable map on a web page that lets people show the location of a sighting;
* A form that collects some other basic data;
* Logging of spatial points and the form data.

Ideally this could be done through a Facebook page as social media will spread this like ... well, like a butterfly migration in a high wind ;). 

Any ideas?
