You can play an important role this year in documenting the Brood XIV 17 year cicada emergence. Brood maps like this one are built using data from scientists and people like you. This year we have an opportunity to build a better Brood XIV map, but the scientists who collect the data will need your help.
Where to post your sightings
The two main web sites where you will be able to post your sightings this year are:
Both sites promise to feature interfaces that will easily allow you to enter your sighting.
In the Massachusetts area (and beyond): Massachusetts Cicadas (Jerry Bunker).
In the Mid-Atlantic region: Cicadas.info.
Where ever: Our 2008 17 Year cicada message board. Use this one for informal sightings only.
