County Checklists

Clickable Map of the U.S.
For a checklist of all species reported in a particular county, first select a state from the map above or the list below. On the resulting page, select the county or region for which you wish to view a checklist. Note that data are not as comprehensive for some counties as they are for others. If you have verifiable species records for a particular county, we encourage you to report them (see our FAQ entitled How Can I Report a New County Record for a Moth or Butterfly?).
