We are working on a new version of the Butterflies and Moths of North America (BAMONA) website and underlying database, with plans for a 2016 release. The site will be responsive (mobile-friendly) and have other improvements.
Due to limitations of the existing technology, we recently had to replace the Google map base layer with a layer from Open Street Map. When the new BAMONA site is launched, we will be able offer better maps again.
We apologize for the inconvenience.
