I’ve covered some of the concern about disappearing fireflies before here at the Bug Blog. Because fireflies tend to live and breed in damp and swampy areas, they have been very affected by habitat loss as the country urbanizes.
In general, though, we just don’t know very much about firefly history and distribution. The Boston Museum of Science is asking for volunteers to help observe and report on firefly populations in their area.
There is also a “frequently asked questions” page that covers what volunteers need to know. Sign up for your account and participate in understanding (and saving) these little six-legged bits of magic in the summer!
BTW, The NSCU Insect Museum Blog covers several other Citizen science/Insect monitoring projects.
