Compiled from Kelly Richers' California Moth Specimen Database. Kelly has been compiling the database since 1996 from literature sources, museum collections, and (I believe) novel collections. These lists are probably not comprehensive (if such a thing is possible for such a diverse group of organisms), but given Kelly's dedication and the degree of sampling in the state, it's probably pretty close at the state and regional level, and approaching that state at the county level. All errors are my own, and if you find any, please let me know.
